Heat and Temperature

Emerson places a beaker of water on a hotplate and turns the hotplate on. The temperature in the room is 25 ºC. After the water heats to 75 ºC, she adds pieces of ice to the beaker.

Which of the following describes a transfer of heat energy that occurs during this experiment?

• from the air to the water

• from the ice to the beaker

• from the water to the ice

• from the water to the hotplate
