Worked Solution

Step 1: Identify that temperature is a measure of hotness (both are 100°C). Step 2: Recall that heat energy depends on the mass/volume of the substance. Step 3: Since the bowl has 500 ml and the mug has 100 ml, the bowl has more heat energy.

Correct answer: The water in the bowl has more heat than the water in the mug.
