Concept:A calorimeter is the container used to measure quantities of heat
Q.
Explanation:Heat
Q is a form of energy transferred from a hotter body to a colder body.
To measure heat involved in a physical or chemical change, the change is performed inside a special insulated container.
This container is called a calorimeter.
It minimises heat exchange with the surroundings so that accurate readings are obtained.
Inside the calorimeter, the temperature change
ΔT is observed and used to calculate the heat
Q from
Q=mcΔT.
Now consider the other options.
A thermometer only measures temperature, not heat quantity.
A measuring cylinder measures volume.
A meter rule measures length.
Therefore, only a calorimeter is designed to measure quantities of heat
Q.
Answer: C. Calorimeter
