They speed up and moves faster and faster.
The Sun heats up the Earth At least, mostly It heats up the molecules in the air, which also explains why it's colder the higher you are- there are less air molecules for the Sun to heat up
It heats up.
The surface of the moon heats up.
evaporation. This happens when sunlight heats up the water molecules, causing them to gain enough energy to escape into the air as water vapor.
Air loses density when it heats up because the air molecules become more energetic and spread out, resulting in a decrease in density. Conversely, air becomes more dense when it cools down because the molecules lose energy and come closer together.
When a noble gas is heated, its molecules move faster (this is the same as saying that the gas heats up).
What do you think happens when some air heats up and other air is cool?
it heats up
It heats up
heat because as it heats up the molecules they separate and start to move

it vibrates the water molecules in the food and heats it up
It heats up.
it heats up
All of the molecules heat up witch causes it to draw in moisture
it heats up
The density decreases.
