How atoms and molecules are affected by heat?

Answer 1

Their speed, energy, and the total volume increases.

When we heat up substances, we are transferring energy in the form of heat to them. The molecules have to do something with the energy, so usually they will start to vibrate faster (more kinetic energy), and in some cases, lose electrons (become ionized), but that process takes up a lot of energy.

Also, the volume of a substance will increase, while keeping the mass the same, and so its density decreases. This is why hot air floats.

Answer 2

Atoms and molecules are affected by heat through the increase in their kinetic energy, causing them to move faster and collide more frequently. This can lead to changes in their arrangement, such as breaking chemical bonds or changing states of matter.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
