Answer:

Heat energy will flow from one to the other.

Explanation:

This is called "heat transfer" or the transfer of heat, when you place two things together the object was a warmer temperature will transfer it's heat into the object with the lower temperature. For example if you put boiling water in a glass bowl the heat from the water will transfer to the bowl increasing it's temperature.

Hope this helps.

Methane can be decomposed into two simpler substances: hydrogen and carbon. Therefore, methane 1. is a gas. 2. cannot be an elem

Reika [66]

Answer: 2. cannot be an element.

Explanation:

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper $Cu$

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: methane $CH_4$

$CH_4\rightarrow C+2H_2$

Thus as it can be decomposed into its constituent elements, it is a compound.

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.

Thus methane cannot be an element.

Energy

Explanation:

Energy is the ability to change the state of bringing about a work leading to movement or generating electromagnetic radiation. There are actually many forms of energy. So, kinetic energy is a form of energy related to the movement of a body. The combustion, in turn, retrieves the potential energy chemical contained in fuels. Solar panels capture light energy to transform it into electrical energy.
