change of state
phase change

Answer 1

Increase in temperature
Change of state
Phase change

Answer 2

when heat energy is added to a system, change in system can be:

• Increase in temperature: If system doesn't absorb the heat energy, then the effect will be increase in temperature.
• Change of state: If system absorbs the heat energy. And energy change in system can change the state of system.
• Phase change: If system absorbs the heat energy then the phase of system can be changed. For example liquid can be converted into vapors by adding heat energy to system.
