Question

A scientist designed a foam container to help keep frozen foods from melting. Which best explains how the foam works? It removes thermal energy from the air inside the container. It removes thermal energy from the frozen foods inside the container. It reduces the amount of thermal energy that is transferred from inside to outside the container. It reduces the amount of thermal energy that is transferred from outside to inside the container.

Answer 1

It reduces the amount of thermal energy that is transferred from outside to inside the container.

Step-by-step explanation:

Remember that thermal energy = heat. Also foam cannot remove thermal energy, it is an insulator meaning it prevents the transfer of thermal energy.

First choice: Foam cannot just remove thermal energy

Second: Again foam does not remove energy

Third: This would mean the heat would continue to stay in the container, leading to the frozen foods melting

Fourth: Correct, it reduces the amount of outside heat from entering the container, thus preventing melting
