Question

Which apparatus is used in the laboratory for measuring the heat capacity of a substance?
1. Manometer
2. Hygrometer
3. Colorimeter
4. Calorimeter

Answer 1

Correct Answer - Option 4 : Calorimeter

The Correct Answer is Calorimeter.

• A calorimeter is an object used to measure the heat of chemical reactions or physical changes as well as the heat potential for calorimetry, or the method of measuring it.
• Among the most popular types are differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters.
• A basic calorimeter is essentially a thermometer that is connected to a metal container full of water suspended over a chamber of combustion.
• It is one of the measurement instruments used in thermodynamics, chemistry, and biochemistry science.

 

• A manometer is a pressure measurement device. A typical simple manometer is made up of a glass U-shaped tube filled with some liquid. Because of its high density, the liquid is usually mercury.
• A hygrometer is a device used to determine the quantity of water vapour in enclosed spaces, air, or soil.
• A colourimeter is a device that calculates the absorption by a particular solution of specific wavelengths of light used in colourimetry.
