what happens when heat is added once the phase change is complete
Answers
Answer:
During a phase change, a substance undergoes transition to a higher energy state when heat is added, or to a lower energy state when heat is removed. Heat is added to a substance during melting and vaporization. Latent heat is released by a substance during condensation and freezing.
When heat is added once the phase change is complete, the temperature does not rise.
- A phase change is a process in which a substance goes from one phase to another.
- The change of phase always occurs with a change of heat.
- It means the energy supplied during the phase change is used only to separate the molecules.
- Since kinetic energy doesn't increase, there is no rise in temperature.
- Heat energy is used to change the bond between the molecules.
- During a phase change, when heat is added a substance undergoes a transition to a higher energy state and to a lower energy state when heat is removed.
- If heat is added, the internal energy increases and vice versa.
