A. Heat equal volumes of 10°C and 20°C water for 15 minutes each.
B. Heat equal volumes of water for 10 and 20 minutes and record any change in the volumes.
C. Heat 100 mL and 300 mL of water and record the temperature when boiling occurs.
D. Heat 150 g and 100 g of water until the containers are completely dry.
