In terms of energy, a liquid will freeze when enough heat energy is removed from it. This will reduce the average kinetic energy of the particles (atoms or molecules).

How do you change solid water to liquid and liquid water to gas?
You can change both of these by increasing or decreasing the speed of the molecules (kinetic energy), or by increasing or decreasing the heat applied (thermal energy). If you want to melt ice, you can increase the kinetic energy by increasing the thermal energy. The opposite occurs if you want to freeze water.
Is Kinetic energy a solid liquid or gas?
Kinetic energy is the energy of motion. Heat is a form of kinetic energy (the movement of individual atoms or molecules) so the liquid phase contains more kinetic energy than the solid and the gas phase has more kinetic energy than the liquid phase. However, kinetic energy can also be imparted to a mass as a whole in which case if the total mass of the phases was constant the this imparted kinetic energy would be the same for all phases.
Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
Does the temperature of a liquid change due to evaporation?
Yes, it decreases. This is because the molecules of the liquid which have higher kinetic energy escape from the liquid, leaving the liquid with molecules having lower kinetic energy. The temperature of any substance is proportional to the kinetic energy of its molecules.
Does a liquid has a low or high kinetic energy?
it really depends. For example, and ice cube has low kinetic where as steam has high kinetic energy
What causes particals to evaporate and leave the surface of a liquid?
Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)

What effect does liquid nitrogen have on molecular kinetic energy?
Temperature is a measure of kinetic energy. Because liquid nitrogen is very cold, a system's kinetic energy will be collisionally transferred to the added liquid nitrogen. Thus, in general, adding liquid nitrogen will decrease a system's kinetic energy. (There are some exceptions where the system has less kinetic energy than the liquid nitrogen, such as liquid helium.)
Why does raising the temperature causes a liquid to boil?
Decreasing the pressure -APEX
What liquid does not freeze at -78 degrees Celsius?
All liquids evaporate. Evaporation occurs when the liquid molecules at the surface have sufficient kinetic energy to escape from the liquid as a gas. Since all liquids have kinetic energy (by kinetic model of matter), it should be alright to say that all liquids evaporate. This is unless you cool the liquid (somehow) to the absolute zero so that the liquid molecules lose all their kinetic energies, which is something scientists have not achieved so far,
Why is kinetic energy more in liquid state?
Than in ??what?? state Kinetic energy is greater in liquid state because the liquid substance is moving. If the kinetic energy was less than in liquid state, the object of the state would become solid.

Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
How does evaporation?
Evaporation is a spontaneous phenomenon. The molecules in the liquid possess kinetic energy. All the molecules donot possess the same kinetic energy. The molecules with higher kinetic energy are on the surface of liquids. They can readily overcome the intermolecular attractions and escape into the atmosphere. This phenomenon is known as evaporation. As the molecules with higher kinetic energy keep on escaping the whole kinetic energy of the liquid is lowered. Since energy is directly proportional to temperature. Thus evaporation causes cooling effect.
Does the temperature of a liquid change due to evaporation?
Yes, it decreases. This is because the molecules of the liquid which have higher kinetic energy escape from the liquid, leaving the liquid with molecules having lower kinetic energy. The temperature of any substance is proportional to the kinetic energy of its molecules.
When do liquids gain kinetic energy?
kinetic energy is energy in the form of motion... in other words a liquid must be moving to have any kinetic energy
Which are the first particles to evaporate from a liquid?
The particles that evaporate from a liquid are on the surface of the liquid.
