The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.

How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
How can the temp of a substance remain the same if it is absorbing energy?
The temperature of a substance can remain the same while absorbing energy if it is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed energy is used to break intermolecular bonds rather than increase the kinetic energy of the particles, which keeps the temperature constant.
When heat flows from a hot object to a cold object the temperature of the cold object increases while the temperature of the hot object is what?
The temperature of the hot object will be reduced unless it is undergoing a phase change - in which case it may remain at the same temperature until the phase change is complete - and then drop in temperature if the cold object has not reached the same temperature.
What is the phase in which substances change directly from a solid to a gas?
i would assume that sublimation,solid to gas,would be the same answer when going from a gas to a solid.
What reaction of matter will stay the same during a physical change?
The chemical composition of the matter will stay the same during a physical change. Only the physical properties, such as shape, size, or phase, will be altered without affecting the chemical composition of the substance.
What happens to a substances temperature during a phase change?
stays the same
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.
Which stays the same when a substance switches from liquid to gas?
During the phase change, the temperature stays the same.
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.
What happens to energy added during a phase change?
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?

Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
What phase change mean?
changes from one state to another without a change in chemical composition
Can molecules change phase and increase temperature at the same time?
Yes, it is possible.
When water is heated the temp reaches a constant value and forms a plateau on the graph what does the plateau indicate?
It indicates that the temperature does not change during the phase change from liquid to gas until the change is complete. During the phase change, the heat energy added to the water goes into breaking hydrogen bonds between water molecules, so it does not cause an increase in temperature during that time.
How can the temp of a substance remain the same if it is absorbing energy?
The temperature of a substance can remain the same while absorbing energy if it is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed energy is used to break intermolecular bonds rather than increase the kinetic energy of the particles, which keeps the temperature constant.
What rule can you state about the relationship between phase changes and temperature?
As the temperature increases, the phases change from having the slowest amount of molecules to having the fastest amount of molecules (solid-liquid-gas)
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.
