GENERAL KNOWLEDGE

Detailed explanation-1: -A dilatometer is a scientific instrument that measures volume changes caused by a physical or chemical process. A familiar application of a dilatometer is the mercury-in-glass thermometer, in which the change in volume of the liquid column is read from a graduated scale.

Detailed explanation-2: -Answers and Solutions Question: Which instrument is used to measure changes in volume of substances ? Answer: Dilatomeater is used to measure change in volume of a substance.

Detailed explanation-3: -When for example sand, glass or metal is heated, the material is expanded. This expansion can be measured by so-called dilatometry. The results from such a measurement provide information on the physical properties of the material such as, for example, the expansion coefficient, the softening temperature, etc.

Detailed explanation-4: -Measuring cylinder, pipette and measuring flask are used to measure the volume of the given liquid whereas vernier calliper is used measure the length of the object.
