Unit 9 Lesson 3 What Is Heat?

Daniel uses a thermometer to take a single reading of the water in a beaker. What is Daniel measuring?

• conduction rate

• amount of energy transferred from the water to the beaker

• amount of energy transferred from the beaker to the water

• amount of heat energy of the water

Abd Elrahman knows that heat energy can move between substances. For example, warm water can warm his hands. Which condition must be present for the transfer of energy between two substances to take place?

• The objects must both be solids.

• The objects must transfer energy without the use of matter.

• The objects must be different temperatures.

• The objects must be the same temperature.

On a warm sunny day, a lizard sits on a rock. Which word explains why the lizard feels heat from the sun?

• convection

Maya knows that conduction is a form of heat energy transfer. Which transfer of heat energy is made through conduction?

• hand heats a snowball

• sun warms a greenhouse

• boiling water heats pasta

• radiator warms a home
