Science Formative 7

When two materials that are in contact have the same temperature, the materials are said to be in thermal ___________.

Heat always moves from ________ objects to ________ objects.

• warmer, cooler

• cooler, warmer

• larger, smaller

• smaller, larger

A hot iron is turned off and cools down to room temperature. The iron cools because __________.

• the iron does not hold heat very well

• the room transfers cold energy to the iron

• thermal energy is transferred from the warm iron to the cooler room

Why would wearing several layers of clothing keep you warmer than wearing one heavy sweater?

• Layers of clothing trap layers air which act as an insulator.

• Layers of clothing trap layers of air which act as a conductor.

• The layers of clothing are thicker than the sweater.

• The layers of clothing allow the thermal energy to transfer through easily.
