• conduction
• convection
• radiation
• transformation

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?

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.

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.
