Answer :
A piece of sodium metal is dropped into a calorimeter filled with water, hydrogen gas evolves. The temperature of the mixture rises because As an intensive physical property.
Calorimeter, device for measuring the heat developed throughout a mechanical, electric, or chemical reaction and for calculating the heat ability of substances. Calorimeters have been designed in splendid range.
The frame at better temperature releases heat while the body at lower temperature absorbs heat. The principle of calorimetry shows the regulation of conservation energy, i.e. the overall warmness lost through the new frame is same to the full warmth won by way of the cold body.
The primary ice calorimeters have been built based on Joseph Black's idea of latent warmness, introduced in 1761. Antoine Lavoisier coined the time period calorimeter in 1780 to explain the apparatus he used to measure warmth from guinea pig breathing used to melt snow.
