Answer:
Student 3
Explanation:
This question lets us know something about how the density of a gas varies with temperature.
When a gas is heated, its molecules spread out and expand. When this happens, the volume of the gas increases. Remember that density is defined as mass/volume. Thus as the volume increases, the density of the gas decreases.
Therefore, the carbon dioxide rose up because the heat expanded the gas and it became less dense.
Answer: the process by which cells use oxygen to break down sugar and obtain energy.
Chemical energy is kept inside the bonds that are connected to withatoms with other atoms and molecules with other molecules.
Because chemical energy is kept in likestorage. It is an shape of potential energy.
When a chemical reaction takes place, the stored chemical energy is let out.
