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 able to produce a larger quantity of food through the process of a chemical reaction.
B.
It is designed to insulate thermal energy from moving from one medium into another.
C.
It is designed to control when thermal energy is produced and where it can flow.
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, based on the provided information about how it functions, is:

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

This statement reflects the mechanism of the heating vessel, as it controls the activation of the chemical reaction between water and calcium oxide, which produces heat at a desired time for heating the soup.
