Question

The apparatus used to measure heat is called a ----------------

• A. Thermometer
• B. Microscope
• C. Calorimeter
• D. Screw gauge

Answer 1

The correct option is C

Calorimeter

Explanation for Correct answer:

In case of option C.

Calorimeter:

1. A calorimeter is a device that is used to measure the amount of heat involved in a chemical or physical process.
2. When a reaction occurs in solution in a calorimeter, the heat produced by the reaction is taken by the solution, which thereby increases its temperature.
3. The types of calorimeters are differential scanning calorimeters, titration calorimeters, isothermal micro calorimeters, and accelerated rate calorimeters.
4. Hence, option C is the correct option.

Explanation for incorrect answers:

In case of option A.

1. A thermometer is a kind of instrument used to measure temperature.
2. Thus, option A is an incorrect option.

In case of option B.

1. It is an optical instrument used for viewing very small, micro-objects, such as mineral samples or animal cells, magnified several hundred times.
2. Thus, option B is an incorrect option.

In case of option D.

1. It is an instrument that is used for measuring the diameter of thin wires, the thickness of small sheets, etc.
2. Thus, option D is an incorrect option.

Hence, the correct option is option C.
