Sometimes heat energy is added but the temperature stays the same when is this?
During a phase change.
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
Why does the temperature of ice decrease as it melts?
The temperature doesn't decrease it stays the same while it is melting. Because temperature is heat which is Kinetic Energy (KE) so when the temperature changes the KE changes. A change of state like ice to water or water to steam or vice versa is a state change or a change in potential energy (PE). They both can'y change at the same time so when the ice is melting the PE is changing and the KE is staying the same. ultimately you can have ice at 0 degrees celsius and water at 0 degrees celsius. This happens if there is the same amount of heat added during the state change as before. sources: chemistry class
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
What happens to substances temperature during a change of state?
Temperature remains constant
Does the temperature increase decrease or stay the same during a change of state please say which or all?
Yes.
What happens to a substances temperature during a phase change?
stays the same
Does physical state of matter always change during a chemical change?
No. Two elements of the same state can combine and still be in the same state in the end product.
Which stays the same when a substance switches from liquid to gas?
During the phase change, the temperature stays the same.
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.
Sometimes heat energy is added but the temperature stays the same when is this?
During a phase change.
What does matter can change state mean?
The same substance can exist either as a solid, liquid or a gas and can change state depending on the temperature or external pressure.
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.

Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
Could a phase graph with little temperature increase and a lot of heat be the same as latent heat?
Yes. Strictly speaking there should be no temperature change during a phase change.
