Question

A student pours ammonium nitrate into a container of room temperature water. The student stirs the mixture with a stirring rod and then feels the outside of the container, which is cold to the touch. Which material is part of the system that absorbed heat?
the water

the air

the stirring rod

the container

Answer 1

The material which is part of the system that absorbed heat is; The water.

Discussion:

According to the question;

• Water was initially at room temperature.
• We know by convention, ammonium nitrate is a cold substance.

In essence, the heat liberated from the system must have been absorbed by the water so that the outside of the container after mixing becomes cold.

This is so because water has a high specific heat capacity.

Answer 2

The material that absorbs the heat of the system is water owing to its high specific heat capacity.

The specific heat capacity of a substance refers to the amount of heat that is capable of increasing the temperature of 1 Kg of a body by 1 K. The higher the specific heat capacity, the more the amount of heat that the body can absorb without temperature change.

The material that absorbs the heat of the system is water because water has a higher specific heat capacity than all the other materials present.
