When a sample of liquid is cooled its thermal energy?
When a sample of liquid is cooled its thermal energy goes to its surroundings
What happens when thermal energy is added to a liquid?
it heats up
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
How can a liquid expand without changing state?
A liquid can expand when thermal energy is absorbed which is known as thermal expansion, but the thermal energy is not enough to change the liquid's state. When there is enough thermal energy, the liquid may change to a gas if the particles move fast enough to escape the liquid or it may change to a solid if the thermal energy is released from the matter.
When a liquid becomes a solid where does the heat energy in the liquid go?
A gas has more heat energy, often called thermal energy, than a liquid, even if both the liquid and gas are at the same temperature. Consider that the gas molecules have more thermal energy than liquid molecules of that same substance. The gas molecules are "free" to move around more because they have more kinetic energy than molecules of the liquid. And kinetic energy is function of thermal energy. If we consider the case of water molecules to illustrate our point, when a pan of water is boiling, the water molecules escaping the pan as a gas have more kinetic energy than the ones making up the liquid water that is still in the pan. Also consider the case of water that is evaporating. Wet your finger and blow on it. The liquid water on your finger cools as the evaporating water molecules take thermal energy from that liquid to make their change of state possible. It takes an increase of thermal (heat) energy to change a liquid into a gas.

What happens to the thermal energy of a liquid as it vaporizes?
It increases
When adding thermal energy to a liquid what happens?
it heats up

What happens to the thermal energy of a gas when it condenses and forms a a liquid?
The energy is released into the air.
When a liquid is cooled the molecules in that liquid?
I assume you mean what happens to the molecules... They slow down due to the loss of kinetic energy when the liquid is cooled. When they are sufficiently cooled as to cause freezing, that's a different story.
What happens if we remove thermal energy to a liquid.?
It will get colder. It also might freeze.
Why does water get cooled in evaporation?
It takes energy to boost a liquid or solid into a gaseous state, so an evaporating substance must aborsb thermal energy.
What happens if we add thermal energy to a liquid?
It will get hotter. Eventually it may evaporate.
What happens when a liquid doesn't have thermal energy?
Any object above zero kelvin - in other words, any object - has thermal energy. If you cook down a liquid - reduce its thermal energy - it will sooner or later get cold enough to become a solid.
What happens when you remove thermal energy from a gas?
It turns into a liquid. Just like if you were to remove thermal energy from a substance the atoms will slow down.
