How does the mass of a substance affect the amount of thermal energy it can store?

• More mass means less thermal energy storage.

• More mass means more thermal energy storage.

• Mass does not affect thermal energy storage.

• Mass only affects thermal energy storage in solids.

Design an experiment to test how different materials affect the rate of heat transfer.

• Use identical containers with different materials and measure temperature change over time.

• Use different sized containers and measure the time it takes to cool.

• Use the same material and measure the time it takes to heat up.

• Use different liquids and measure the temperature change.
