Why does temperature no change during energy phase change?
During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
What happens to a substances temperature during a phase change?
stays the same
What does not change when a substance changes matter?
During a physical change, the matter of what the substance is made out of doesn't change.
What happens during a physical change?
In a physical change, color, shape, state, temperature, or texture can change. None of these effect the changes substance's chemical properties.
Explain why the temperature of Wax remains constant during solidification?
it's because it releases the latent heat of fusion. Latent heat means energy is given out when a substance changes from liquid to solid without a change in temperature. and the transfer of energy doesnt change the KE of the particles, so the temperature remains unchanged. lanten heat gives rise to the change in PE of the particles during the change of state only
What properties do not change when matter changes state?
During phase changes the temperature of a substance does not change.
What During a phase change the temperature of a substance .?
The temperature* remains unchanged. * The heat (energy) content changes.
Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What happen to the temperature of a substance during a phase change?
The temperature* remains unchanged. * The heat (energy) content changes.
What changes during melting?
The substance absorbs the heat of fusion. The temperature does not go up, but the form of the substance changes.
What do you think will happen to the temperature of a substance during a phase change?
Typically, the temperature doesn't change during a phase change.
During a temperature change what is happening to the substance?
A change of phase: melting, evaporation, liquefaction or chemical changes as thermal dehydration, thermal decomposition, oxydation, etc.
Why does temperature no change during energy phase change?

The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
What are the characteristic of physical change?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
