Answer: Option (c) is the correct answer.
Step-by-step explanation:
A device with the help of which energy produced or absorbed or specific heat of a chemical reaction is measured is known as calorimeter.
Whereas a thermometer is used to measure the temperature of human body.
For example, when a person is having fewer then thermometer is used to check the temperature of his body.
On the other hand, a molemeter is used to measure the frequency and output voltage for an alternate current source.
Thus, we can conclude that the common device used for measuring heat transfer for chemical reactions called calorimeter.
