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. A scientist designed a foam container to help keep frozen foods from melting. Which best explains how the foam works?

Answer 1

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

Foam acts as an insulating material with low thermal conductivity, so it slows the flow of heat from the warmer outside into the cold interior, helping frozen foods stay frozen.
