Answer: The answer is probably B because most of the precipitation and evaporation in the water cycle happens over the oceans. Including, about 78 percent of the precipitation and 86 percent of evaporation.

The statement about the ocean is true is most evaporation and precipitation in the water cycle occur over the ocean. Therefore, option 2 is correct.

The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.

The water cycle is composed mostly of four processes: evaporation, convection, precipitation, and collection. When water in rivers, lakes, or the ocean is heated by the sun and turned into vapour or steam, this process is known as evaporation. The river, lake, or ocean releases water vapor or steam into the atmosphere.

The hydrologic cycle is crucial because it determines how water gets to people, plants, and other species. In addition to supplying water for people, animals, and plants, it also transports nutrients, diseases, and sediment into and out of aquatic habitats.

Thus, option 2 is correct.

Answer:

116,823 J

Explanation:

formula : q=m C delta T

q = heat = unknown

mass = 100 g

C = specific heat = 4.2 J/K*g

delta T = temperture in Kelvins: 5 + 273.15 = 278.15 K

q = (100 g) ( 4.2 J/K*g) (278.15 K) = 116,823 J

Explanation:

1-burning fossil fuels.

Sulfur dioxide released by the burning of fossil fuels like coal, petroleum is the major cause of air pollution.

Gases emitted from vehicles including trucks, jeeps, cars, trains, aeroplanes cause an immense amount of pollution.

2-Agricultural activities

Use of insecticides, pesticides and fertilizers in agricultural activities release harmful chemicals into the air and can also cause water pollution.

3-Exhaust from factories and industries

Manufacturing industries release a large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air thereby depleting the quality of air.

Petroleum refineries release hydrocarbons and various other chemicals that cause air pollution.

4-Mining operations:

Mining is a process wherein minerals below the earth are extracted.

During this process dust and chemicals are released in the air causing massive air pollution.

A force that resists motion when objects touch is friction. Frictional force is the force that prevents an object from moving.

The term friction is defined as the force that opposes the motion of a solid object over another. There are four types of friction that are static friction, sliding friction, rolling friction, and fluid friction.

Three factors in particular determine the frictional force between two bodies: The adhesion between body surfaces, the surface roughness, and the deformation of bodies are all factors.

Frictional force is the force that prevents an object from moving. The imperfections on the two surfaces in contact are what produce friction. The type of surfaces in contact affects friction.

Thus, A force that resists motion when objects touch is friction.

Answer:

7.08 L

Explanation:

From the question given above, the following data were obtained:

Initial mole (n₁) = 1.2 moles

Initial volume (V₁) = 5 L

Final mole (n₂) = 1.2 + 0.5 = 1.7 moles

Final volume (V₂) =?

From ideal gas equation,

PV = nRT

Divide both by n

PV / n = RT

Divide both side by P

V / n = RT/P

RT/P => constant

Therefore,

V₁ / n₁ = V₂ / n₂

With the above formula i.e

V₁/n₁ = V₂/n₂

We can obtain the final volume of the gas as follow:

Initial mole (n₁) = 1.2 moles

Initial volume (V₁) = 5 L

Final mole (n₂) = 1.7 moles

Final volume (V₂) =?

V₁/n₁ = V₂/n₂

5 / 1.2 = V₂ / 1.7

Cross multiply

5 × 1.7 = 1.2 × V₂

8.5 = 1.2 × V₂

Divide both side by 1.2

V₂ = 8.5 / 1.2

V₂ = 7.08 L

Therefore, the final volume of the gas is 7.08 L

Explanation:

Thermal energy is transferred to material,the motion of its particles speeds up and it's temperature differences.Insulating materials are bad conductors and so this reduces the heat loss by conduction.The material also prevents air circulating inside the cavity,therefore reducing heat loss by convection.Heat loss through the roof can be reduced by laying loft insulation.

Answer: Decreases across the period and increases down the group

Answer:

as the potential energy decrease the kinetic energy increases

Explanation:

at the cliff it possess maximum potential energy but as it falls it possess maximum Kinetic energy

When the rock is still stationary at a height, it possess all potential energy. As it begins to fall from the height, potential energy decreases and kinetic energy increases.

Energy transformations involve the change of energy from one form to another in accordance with the principle of energy conservation.

For a rock found at a height, all it has is potential energy. This potential energy decreases when the rock begins to fall and kinetic energy increases accordingly.

Hence, for a rock that falls off a cliff, as the potential energy increases, the kinetic energy increases.
