radiation

Question 16

On a hot day, Jenny walked home from the grocery store with a bag of chocolate chips. When she arrived home the chocolate chips had melted in the bag. Why did the chocolate chips melt?

Accepted Answer

Heat transferred from the environment to the chocolate chips.

Answer

Heat evaporated from the bag to the chocolate chips.

Answer

Heat transferred from the chocolate chips to the bag.

Answer

Heat condensed from her hand to the chocolate chips.

Question 17

The diagram , which shows two insulated Styrofoam cups of water connected by an aluminum bar. The thermometers show the temperature of the water in Cup A and Cup B at the beginning of a heat-flow experiment. Which if the following statements is NOT CORRECT?

Accepted Answer

Thermal energy is transferred from Cup A to Cup B by radiation through the aluminum bar.

Answer

Styrofoam Cup A would be cooler to touch than the aluminum bar because it is a better insulator.

Answer

The aluminum bar would be warm to the touch because it is a good conductor of thermal energy.

Answer

Thermal energy is transferred from Cup A to Cup B through conduction in the aluminum bar.

Question 18
