Question

The least count of Beckmann's thermometer is ______. (${0.01}^{o}C$/${0.10}^{o}C$).

Answer 1

A Beckmann thermometer is a device used to measure small differences of temperature, but not absolute temperature values.

The least count of Beckmann's thermometer is ${0.01}^{0}C$.

It is used to determine precisely small changes in temperatures due to elevation of boiling point or depression of freezing point.
