➡️(c) Thermometer can be used to measure temperature of liquid.

➡️A calorimeter has two vessels:

an outer vessel and and inner vessel. The air b/w the two vessels act as a heat insulator, that is, there is no (or minimal) heat exchange

b/w what is inside the inner vessel and the outside environment.

I hope it helps u. And make this answer as brainliest.
