Self-heating cans use the concept of an interior heating vessel that is able to warm up food. The diagram below shows a model of how a self-heating can works.

Question

When the activation button is pressed, the water is released into the calcium oxide. When the water and calcium oxide mix, a chemical reaction occurs and releases heat, which is able to heat the soup in the can. Which statement best describes the interior heating vessel?
A.
It is designed to control when thermal energy is produced and where it can flow.
B.
It is able to produce a larger quantity of food through the process of a chemical reaction.
C.
It is designed to insulate thermal energy from moving from one medium into another.
D.
It is able to regulate the flow of the calcium oxide and water into the food to make it warm.

Answer 1

The best statement that describes the interior heating vessel in a self-heating can is:

A. It is designed to control when thermal energy is produced and where it can flow.

This option accurately reflects the purpose of the interior heating vessel in managing the release of heat from the chemical reaction between water and calcium oxide, ensuring that the heat effectively warms the food in the can.
