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.

What has to be added to a substance to cause a phase change?
Adding or removing energy in the form of heat is needed to cause a substance to undergo a phase change. This extra energy helps break the intermolecular forces holding the particles together in their current phase, allowing them to rearrange into a new phase with different properties.
How can the addition or removal of energy cause a phase change?
The addition of energy (such as heat) to a substance can break the bonds holding its particles together, causing them to move more freely and change phase, for example from solid to liquid. Conversely, the removal of energy can weaken the intermolecular forces, allowing particles to come closer together and change phase, such as from gas to liquid.
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.
Why do substances change phases when energy is added or removed?
When energy is added to a substance, the temperature of the substance increases, causing the particles to gain kinetic energy and move faster, resulting in a phase change. Likewise, when energy is removed from a substance, the temperature decreases, causing the particles to slow down and the substance to change phases. The energy absorbed or released during these phase changes is used to either break or form bonds between the particles.

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.
How do you describe the relationship between phase change and thermal and heat energy?
Phase change is the process where a substance changes from one state to another, such as solid to liquid. During phase change, thermal energy is absorbed or released without a change in temperature, as the energy is used to break or form intermolecular bonds. Heat energy is the transfer of thermal energy between objects due to a temperature difference, and it can cause phase changes by providing the energy needed to overcome intermolecular forces.
How does the energy of a system change during phase change?
energy is either absorbed or released during a phase change
How does the the energy of a system change during a phase change?
energy is either absorbed or released during a phase change
What determines the direction of energy transfer in a phase change?
light is form of energy then light is reflected at boundary of rarer medium and denser medium reflected ray is phase change of 180 degree's energy is phase changed direction of energy is opposite of transfer ed way
When substances go directly from the solid phase to the gas phase the phase change is called?
sublimation
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.
The energy involved in a phase change is called the?
Heat associated with phase change is called Latent Heat
How can the addition or removal of energy cause a phase change?
The addition of energy (such as heat) to a substance can break the bonds holding its particles together, causing them to move more freely and change phase, for example from solid to liquid.

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.
