heating point for water - 100°

The melting point (MP) of a substance is the temperature at which it melts. A solid's melting point is a physical characteristic that can be used to identify a substance. Here the correct option is B.

The melting point of a solid is the temperature at which it begins to liquefy. A substance's normal melting point is its melting point under atmospheric pressure. Ice often melts at 0 degrees Celsius.

A physical process called melting or fusing causes a substance to change its phase from a solid to a liquid. This happens when the solid's internal energy rises, usually as a result of heat or pressure being applied, which raises the substance's temperature to the melting point.

Thus the correct option is B.

Explanation:

General Rules. In general, the electropositive character of the oxide's central atom will determne whether the oxide will be acidic or basic. The more electropositive the central atom the more basic the oxide. The more electronegative the central atom, the more acidic the oxide.

Answer with Explanation:

A "suspension" is said to be unstable because some of its particles settle at the bottom when it is left for some time. One example of this is the "antibiotic suspension." If you might have noticed, the particles settle at the bottom and this is the reason why it is important to shake the medicine before giving it to patients. Another point to consider is the fact that the suspension has a residue when you try to filter out the particles. This means the solute can be separated from the solvent; thus, it cannot be distributed uniformly. So, this makes it unstable.

Explanation:

Invasive species are the non-native species in a particular area, society or environment causing more havoc than good. Invasive species are introduced into the environment through many means which might be intentional and which might not.

One of the reason behind the presence of invasive species in Georgia is to augment the native specie present in Georgia at that time for instance, one of the invasive species mentioned in the question that is "kudzu" was introduced to the environment in Georgia as specie for controlling erosion.

Although some invasive species were introduced into Georgia by mistake, some invasive species were also introduce because of the need for new Specie in the environment.

Answer:

1.006 * 103

Explanation:

Add the number between 1 and 9 and add a decimal accordingly . so the answer is 1.006 multiplied by 10 raised to power 3

Potential energy : energy obtained due to height or position (the force of gravity)

 PE = mhg

g = acceleration due to gravity  (m/s²)

h = height (m)

m = mass (kg)

1. Known

m = 0.5 kg

h = 1 m

g = 9.8 m/s²

then :

[tex]\tt PE=0.5\times 1\times 9.8=4.9~J[/tex]

Kinetic energy is the energy gained by an object's motion

KE = 1/2 mv²

2. To find KE, the required data are the mass and velocity

Answer:

₈₈Ra²²⁶  →   ₈₆Rn²²²  + ₂He⁴  + energy

Explanation:

Alpha beta and gamma radiations are the examples of ionizing radiations.

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles having  two proton and two neutrons. It is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4  and atomic number less than 2 as compared to parent atom.

For example:

₈₈Ra²²⁶  →   ₈₆Rn²²²  + ₂He⁴  + energy

Properties of alpha radiation:

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

Another example:

₉₂U²³⁸   →   ₉₀Th²³⁴  + ₂He⁴  + energy

Answer:

Explanation:

The distance covered by an object given it's velocity and time taken can be found by using the formula

Answer:

Explanation:

Oxide has a 2- charge.

Copper (I) Oxide = Cu2O

Copper (II) Oxide = CuO

The formula CuO can not be used to represent both copper I oxide and copper II oxide.

The formula of an ionic compound takes into account the oxidation state and valency of the the metal cation which is usually shown as a Roman numeral in the name of the compound.

For the compound copper I oxide, the correct representation of the compound is Cu2O. This shows that oxygen has a valency of 2 while copper has a valency of 1 in the compound.

The correct representation of copper II oxide is CuO. In the compound, both copper and oxygen have valency of 2.

Answer:

It is true , that the tropical zone experiences the trade winds .

Explanation:

TRADE WINDS -: The trade winds or easterlies are the dominant east-to - west permanent winds that flow in the equatorial area of the Planet (between latitudes 30 ° N and 30 ° S). In the Northern Hemisphere, the trade winds blow primarily from the northeast and from the southeast in the Southern Hemisphere, strengthening throughout the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by sailing ship captains for centuries to cross the world's oceans and have enabled colonial expansion into the Americas and the construction of trade routes across the Atlantic and Pacific oceans. They act as the steering flow for tropical storms in meteorology. developing over the Atlantic , Pacific, and Southern Indian Oceans and landing in North America, Southeast Asia, Madagascar, and East Africa. Under trade wind regimes, shallow cumulus clouds are seen and are capped from being larger by a trade wind inversion induced by downward air aloft from within the subtropical ridge.

When trade winds blow through tropical areas , due to more direct sunlight , air masses heat up across lower latitudes. Those that develop over (continental) land are drier and hotter than those that develop over (maritime) oceans and travel northward to the subtropical ridge 's western periphery. Masses of maritime tropical air are often referred to as masses of commercial air. There are extensive areas of trade winds in all tropical oceans except the northern Indian Ocean.

Hence , the statement is true.
