Heat Energy Transfers

One end of a metal rod is placed over a flame during an investigation. A thermometer is touching the opposite end of the metal rod. Which best describes what is happening during this investigation?

• Convection carries heat to the thermometer

• Radiant energy warms the thermometer.

• Mechanical energy from the flame carries heat to the thermometer.

• Heat from the flame is conducted through the metal rod to the thermometer.

Isabella filled a glass with warm water. She measured the temperature, and it was 30°C. She left the glass on a table in a room that was 20°C. A few hours later, she measured the water temperature again, and it was 24°C. Which BESTexplains why the water temperature changed?

• Energy in the air removed heat from the water.

• Heat energy in the water was destroyed by the glass.

• Heat energy in the water was transferred to the cooler air.

• Energy used by evaporation caused the water temperature to decrease.
