Q: During a phase change, the temperature of a substance:
Solution: During a phase change, the temperature of a substance remains constant while the substance absorbs or releases heat.
Steps: 4
Step 1: Understand what a phase change is. A phase change is when a substance changes from one state to another, like from solid to liquid (melting) or from liquid to gas (evaporation).
Step 2: Know that during a phase change, the substance is either absorbing heat (gaining energy) or releasing heat (losing energy).
Step 3: Realize 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.
