Yes it does. Changing between the forms requires energy to be lost or gained depending on the direction the substance is changing. Changing from solid to liquid or gas and changing from liquid to gas both require inputs of energy to the substance, and changing from gas to liquid or solid or from liquid to solid releases energy from the substance to the environment, all at constant temperature.

∙ 14y agoI would say that is not a very good definition for energy. It is hard to give a precise definition for energy. Energy is a property that is stored in different forms, in different substances. For example, there is energy of movement (kinetic energy), energy of position (potential energy), chemical energy, electrical energy, sound energy, heat energy, and many more. Energy can informally be defined as the "capacity to do work", but this is not very precise, since it requires additional explanations. Energy is required to do many different things - like, to make machines work. You can convert one type of energy to another type, but you can't create energy out of nothing - the total amount of energy in a "closed system" (one with no contact to the outside world) is constant.

∙ 14y agoYes. The molecules of a solid object have less energy than that of a liquid. So when a liquid freezes (turns to a solid) it loses energy.

high temperature gives more kinetic energy for particles in substance to vibrate, allowing it to change state.

What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
Why does the temp of water not increase during a phase change?
These are phase changes - All the energy that is added at this time is used to change the phase of the substance.
What happens when removing Thermal Energy from gold?
Removing thermal energy (or, to be accurate INTERNAL energy since in thermodynamics thermal energy is a deprecated term) will usually cause it to get cooler. If it is near a phase boundary it may, instead cause some of it to change phase (solidify from liquid for example). Since electrical resistance is dependent on temperature, it will also lower the electrical resistance.
Is heat a phase change?
No. Heat is a form of energy.
What is unusual about the phase change of naphthalene?
if napthalene absorbs energy at 250j per minute how much energy is lost to effect the phase
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
Why wouldn't the temperature of a substance change when heated or cooled?
There are two points for most substances where a phase change takes place. The energy used to rearrange molecules, called the heat of entropy, must be added or removed before the phase can change. The substances show little or no temperature change at some point in this process.
When substances go directly from the solid phase to the gas phase the phase change is called?
sublimation
What happens to the energy added during a phase change?
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
How does the the energy of a system change during a phase change?
energy is either absorbed or released during a phase change
How does the energy of a system change during phase change?
energy is either absorbed or released during a phase change

What happens to the energy during a phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
What happens to the energy added during the phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
Why does the temperature not change during a phase change?
During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.
Why do substances exist as gases?
At a given temperature practically all substances become a gas; it is a change of phase.
