Phase changes are not associated with a change in?
Phase changes, such as melting or freezing, are not associated with a change in temperature. Instead, the energy associated with phase changes is used to break or form intermolecular forces between molecules.
When a substance changes from one phase to another what occurs?
Heat is transferred.
What two processes need heat to happen?
Melting, where a solid changes to a liquid state, and vaporization, where a liquid changes to a gas state, are two processes that require heat to happen. These phase changes involve absorbing thermal energy to break intermolecular forces holding the particles together.
What is heat and phase changes?
Heat is a form of energy that is transferred between objects due to temperature differences. Phase changes are transitions between different states of matter, such as solid, liquid, and gas, which occur when heat is added or removed from a substance. These changes are governed by the energy exchange between molecules.
Are phase changes in matter permanent?
No, phase changes in matter are not permanent. They can be reversed by providing or removing energy (such as heat) to the substance. For example, ice can melt into water when heat is applied, and the water can freeze back into ice when it is cooled.
What phase changes release energy?
Gas to liquid change releases energy.
When you heat liquid and it change phase it become a?
When you heat a liquid and it changes phase it becomes a solid.
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)
When you heat a liquid and it changes phase it becomes?
a gas.
What is the name for temperature changes that involve no heat transfer?
Adiabatic processes involve temperature changes that do not involve heat transfer. This means any increase or decrease in temperature is due to internal energy changes within the system, rather than heat being added or removed from the surroundings.
What is unique about temperature during phase changes?
It doesn't change notwithstanding heat energy changes.
Temperature changes are those which do not involve the addition or subtraction of heat?
Adiabatic

When a substance changes from one phase to another what occurs?
Heat is transferred.
What phase changes require the addition of energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
What are two phase changes that occur when matter loses heat energy?
Two phase changes that occur when matter loses heat energy are: Solid to liquid: When a substance loses heat energy, it can transition from a solid phase to a liquid phase. This process is called melting. Liquid to gas: Another phase change that can occur when matter loses heat energy is the transition from a liquid phase to a gas phase. This process is known as vaporization or boiling.
What two processes need heat to happen?
Melting, where a solid changes to a liquid state, and vaporization, where a liquid changes to a gas state, are two processes that require heat to happen. These phase changes involve absorbing thermal energy to break intermolecular forces holding the particles together.
