During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.
What else can I help you with?
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
Why do you think the temperature does not change much during a phase change?
During a phase change, energy is being absorbed or released to break or form intermolecular forces rather than increasing or decreasing the temperature. This energy, known as latent heat, causes the temperature to remain constant until the phase change is complete.
When can you withdraw heat from something without lowering it's temperature?
You can withdraw heat from something without lowering its temperature during a phase change, such as during melting or boiling. As the substance absorbs energy to undergo a change in state, its temperature remains constant until the phase change is complete.
What A steep slope on a phase-change graph indicates?
Different
How can you add heat to a substance without raising its temperature?
One way to add heat to a substance without raising its temperature is by changing its state of matter. This process, known as phase change, involves adding heat energy to a substance to change it from a solid to a liquid or from a liquid to a gas. During this phase change, the temperature of the substance remains constant until the phase change is complete.
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.
Does the temperature of a substance change before the change of state is complete?
No. During a phase change the temperature is constant until the phase change is complete.
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
What happens to a substances temperature during a phase change?
stays the same
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
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.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
What happen to the temperature during phase change?
The temperature remain constant.
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 happens the temperature during a phase change?
nothing
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.
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
