Which option BEST explains how thermal equilibrium interacts with heat transfer between particles?


a

Thermal equilibrium stops the transfer of energy in just one direction when both objects reach the same temperature, but allows their particles to continue transferring that energy back and forth.

b

Thermal equilibrium always transfers energy from the hotter object to the colder one, and increases the energy and speed of moving particles in both objects as the temperature decreases.

c

Thermal equilibrium helps the transfer of energy between the particles of some materials better than others, but always stops the transfer of energy in materials like plastic and wood.

d

Thermal equilibrium quickly transfers energy back to the particles of the object that was originally hotter, and requires that the particles in both objects have reached equal energy and density.

Answers

Answer:

Thermal equilibrium stops the transfer of energy in just one direction when both objects reach the same temperature, but allows their particles to continue transferring that energy back and forth.

Explanation:

a. The transfer of energy occurs until both objects reach thermal equilibrium. But particles are always moving and crashing with each other. TRUE.

b. The heat transfer occurs from the hotter object to the colder one but moving of particles descreases with temperature decreasing. FALSE.

c. Plastic and wood have a poor quality to transfer energy but there is no material that "stops" perfectly the transfer of energy. FALSE.

d. The heat is transferred from the particles of the hotter object to the particles of the colder one. FALSE

atmospheric pressure at elevations of 8000 feet averages about 0.72 atmospheres. Would a cabin pressurized at 500 mm hg meet federal standards

Answers

Answer:

Yes, but it must be kept at that value and do not let it to decrease more.

Explanation:

Hello.

In this case, in order to substantiate whether the cabin meet the federal standards, we need to convert the 500 mmHg to atm and compare the result with 0.72 atm by knowing that 1 atm equals 760 mmHg:

[tex]500mmHg*\frac{1atm}{760mmHg} \\\\=0.66atm[/tex]

Thus, since 0.66 atm is 0.06 atm away from the federal standard we can infer that it may meet the federal standard, however, it would not be recommended to let the pressure decrease more than that.

Yes, the cabin pressurized at 500 mm hg meets federal standards.

1 atm is approximately equal to 760 mm Hg. Therefore, the pressure is:

500 mm Hg / 760 mm Hg/atm ≈ 0.65789 atm

So, the cabin pressure of 500 mm Hg is approximately 0.65789 atmospheres. If the atmospheric pressure at an elevation of 8000 feet averages about 0.72 atmospheres, then the cabin pressure of 0.65789 atmospheres would be lower than the ambient atmospheric pressure.

To meet federal standards, cabin pressure should be maintained at an equivalent pressure that allows occupants to breathe comfortably.

In the acid-base mechanism, the base is a proton acceptor, and the acid is the proton donor. An acid-base reaction is visualized as the reaction in which proton transfer takes place. However, in a nucleophilic substitution reaction, the nucleophile attacks a substrate (usually an electrophile), and the leaving group is removed from the substrate as a weaker nucleophile. The nature of the reactants determines whether a reaction will proceed as an acid-base reaction or a nucleophilic substitution reaction. Classify each reaction as a nucleophilic substitution reaction or an acid-base reaction.

a. CH3CH2O-+CH3Br → CH3CH2OCH3+Br-
b. CH3CH2OH+HCl → CH3CH2Cl+H2O
c. CH3COOH+NaOH → CH3COONa +H2O
d. CH3CH2CH2Br+HCN→CH3CH2CH2CN+HBr
e. CH3CH2OH+KOH→CH3CH2OK +H2O

Answers

Answer:

a) nucleophilic

b) Acid-base

c) Acid- base

d) nucleophilic

e) Acid-base

Explanation:

A nucleophilic reaction is one in which a nucleophile attacks a substrate and a leaving group departs from the substrate.

Reactions (a) and (d) are nucleophilic reactions since the Br- is the leaving group in the both reactions.

Reactions (b) (c) and (e) are acid-base reactions since they involve salt and water as products.

Explanation:

The mass of the object can be found by using the formula

[tex]m = \frac{f}{a} \\ [/tex]

where

f is the force

a is the acceleration

From the question we have

[tex]m = \frac{6}{12} = \frac{1}{2} \\ [/tex]

We have the final answer as

0.5 kg

Hope this helps you

Answer:

The mass of object is 0.5 Kg.

Explanation:

Given data:

Acceleration of object = 12.0 m/s²

Force on object = 6.0 N

Mass of object = ?

Solution:

Formula:

F = m×a

F = force

m = mass

a = acceleration

Now we will put the values in formula.

6.0 N = m  × 12.0 m/s²

m =  6.0 N / 12.0 m/s²  

  ( N = kg.m/s²)

m = 0.5 kg

The mass of object is 0.5 Kg.

the kind of bond present in CUSO4.5H20​

Answers

Answer:

Both ionic bonds and covalent bonds (coordinate and non-coordinate) are present in crystalline [tex]\rm CuSO_4\cdot 5\, H_2O[/tex].

Explanation:

[tex]\rm CuSO_4\cdot 5\, H_2O[/tex] can be formed by adding water to the anhydrous salt [tex]\rm CuSO_4[/tex].

[tex]\rm CuSO_4[/tex] itself is an ionic compound consisting of [tex]\rm Cu^{2+}[/tex] ions and [tex]\rm {SO_4}^{2-}[/tex] ions. Ionic bonds are present between these ions. However, within each sulfate [tex]\rm {SO_4}^{2-}[/tex] ion, covalent bonds connect the central sulfur atom to each of the oxygen atoms.

Water molecules [tex]\rm H_2O[/tex] are highly polar. Partial negative charges surround the oxygen atom in each water molecule.

When water is added to anhydrous [tex]\rm CuSO_4[/tex], the negatively-charged portion of these [tex]\rm H_2O\![/tex] molecules would be attracted to the positively-charged [tex]\rm Cu^{2+}[/tex] ions in [tex]\rm CuSO_4\![/tex].

Lone pairs on oxygen atoms in [tex]\rm H_2O\!\![/tex] would form coordinate covalent bonds with [tex]\rm Cu^{2+}\![/tex] ions. (These bonds are considered "coordinate" because both electrons in each of these bonds come from the oxygen atom, not the [tex]\rm Cu^{2+}[/tex] ion.) That would produce coordination complexes with one [tex]\rm Cu^{2+}\!\![/tex] ion and five [tex]\rm H_2O\!\!\![/tex] "ligands" each.

Because the [tex]\rm H_2O[/tex] ligands carry no electric charge, each of these complexes would also carry a charge of [tex](+2)[/tex] (same as the charge on one [tex]\rm Cu^{2+}\!\![/tex] ion.) Ionic bonds would be present between the positively-charged coordination complexes and the negatively-charged [tex]\rm {SO_4}^{2-}[/tex] ions.

Summary:

Covalent bonds are present within [tex]\rm {SO_4}^{2-}[/tex] ions and [tex]\rm H_2O[/tex] ligands.Coordinate covalent bonds are present between [tex]\rm H_2O[/tex] ligands and [tex]\rm Cu^{2+}[/tex] ions.Ionic bonds are present between [tex]\rm {[Cu\, (H_2O)_5]}^{2+}[/tex] coordination complexes and sulfate ions [tex]\rm {SO_4}^{2-}[/tex].

The heat of fusion for naphthalene is 0.148 kJ/g. Calculate the heat energy in joules required to melt 52.95 g of naphthalene.

Answers

Answer:

7836.6 J

Explanation:

The following data were obtained from the question:

Heat of fusion (Hf) = 0.148 KJ/g

Mass (m) = 52.95 g

Heat (Q) required =..?

The heat (Q) required to melt the sample of nephthalene can be obtained as follow:

Q = m·Hf

Q = 52.95 × 0.148

Q = 7.8366 KJ

Finally, we shall convert 7.8366 KJ to Joule (J) in order to obtain the desired result. This can be obtained as follow:

1 kJ = 1000 J

Therefore,

7.8366 KJ = 7.8366 KJ × 1000 J / 1 KJ

7.8366 KJ = 7836.6 J

Therefore, 7.8366 KJ is equivalent to 7836.6 J

Thus, 7836.6 J of heat energy is required to melt the sample of nephthalene.

The heat required for melting of 52.95 g of naphthalene has been 7.8366 kJ.

The heat of fusion has been the energy required by 1g for the change in the substance.

The heat required to melt naphthalene can be given as:

Heat = mass × Heat of fusion

The given mass = 52.95 g

The heat of fusion = 0.148 kJ/g

The heat required can be given as:

Heat = 0.148 × 52.95 kJ

Heat = 7.8366 kJ.

The heat required for melting of 52.95 g of naphthalene has been 7.8366 kJ.

The same ball is hit again and experiences a net force of 3.5 N instead. What is the acceleration of the volleyball?

Answers

Answer:

I hope this helped :)

Explanation:

a=f/m

a=3.5N/.25 kg

a=14m/s2

The acceleration of the volleyball is 14 m/s²

A force is defined to be a pull or a push acting on an object. The force exerted on an object can be said to be determined if the mass of the object is known.

It can be calculated by using the expression;

Force (F) = mass (m) × acceleration (a)

From the given information;

The net force acting on the ball after it hits again = 3.5 N

Let assume that the mass of the ball is 0.25 kg since it is not given

The acceleration of the above expression can be computed as:

acceleration (a) = Force (F) / mass (a)

acceleration (a) = 3.5 / 0.25

acceleration (a) = 14 m/s²
