Q: What happens to the temperature of a substance during a phase change?
Solution:
During a phase change, the temperature of a substance remains constant while heat is added or removed.
Steps: 4
Show Steps
Step 1: Understand that a phase change is when a substance changes from one state to another, like from solid to liquid or liquid to gas.
Step 2: Recognize that during a phase change, the substance is absorbing or releasing heat energy.
Step 3: Note that even though heat is being added or removed, the temperature of the substance does not change during this time.
Step 4: Remember that the temperature will only change once the phase change is complete.
