During a change of state, such as melting or boiling, heat is either absorbed or released. When a substance changes from a solid to a liquid or from a liquid to a gas, heat is absorbed to break the intermolecular forces holding the molecules together. Conversely, when a substance changes from a gas to a liquid or from a liquid to a solid, heat is released as the intermolecular forces are strengthened.

What happens to metal railroad tracks during the heat of a summer day?
The rails expand during the heat of a summer day.
What is a good sentence for latent heat?
Latent heat is the energy absorbed or released by a substance during a phase change without a change in temperature.
Why does the temperature remains constant during the change of state?
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
What happens to snow molecules during phase change?
During a phase change from solid snow to liquid water, the snow molecules absorb heat energy and gain enough kinetic energy to break their bonds and transition into liquid form. This process is called melting.
What is phase change number?
The phase change number is a dimensionless number used in heat transfer that represents the ratio of sensible heat transfer to latent heat transfer during a phase change process. It helps quantify the relative importance of sensible and latent heat transfer mechanisms.
What happens during the change in energy?
heat is produced
What happens to the temperature during a phase change?
The temperature* remains unchanged. * The heat (energy) content changes.
What happens when you take the heat away from a substance?
Physical change
What happens to temperature during a phase change?
During a phase change, the temperature remains constant as the substance absorbs or releases heat energy to change from one phase to another. This is because the energy is used to break or form intermolecular bonds rather than raise or lower the temperature.
Heat is eliminated during the process of freezing this loss of heat is considered what kind of change?
This loss of heat is considered a physical change.
What happens when Accidental breeding during a dogs first heat?
Pregnancy
What is the two states of heat?
The two states of heat are latent heat and sensible heat. Latent heat is the heat absorbed or released during a change of phase, such as melting or boiling. Sensible heat is the heat exchange that causes a change in temperature without a change in phase.
What happens to heat during a change of state?
During a change of state, such as melting or boiling, heat energy is absorbed or released without a change in temperature. This heat energy is used to break the intermolecular forces holding the particles together, allowing them to move into a new arrangement. Once the change of state is complete, the temperature resumes changing.
Heat that causes a substance to change form is called?
The heat that causes a substance to change form is called latent heat. This heat is absorbed or released during a phase change, such as melting, freezing, vaporization, or condensation, without causing a change in temperature.
What happens to energy when a material changes state?
During the state change, it's kinetic energy stays constant as well as it's heat. But potential energy is the one to rise.
What happens to metal railroad tracks during the heat of a summer day?
The rails expand during the heat of a summer day.
What happens during a phase change as heat is added to a water sample?
As heat is added to a water sample during a phase change, all of that heat goes into changing the phase, say from solid ice, to liquid water, and as a consequence, the TEMPERATURE of the sampleDOES NOT CHANGE.
