what is principle of method of mixtures? where does it use?
Answers
Explanation:
The principle of the method of mixtures states that the heat lost by a hot body is equal to the heat gained by the cold body when they are mixed together and attain the same temperature.
A method of determining the heat of fusion of a substance whose specific heat is known, in which a known amount of the solid is combined with a known amount of the liquid in a calorimeter, and the decrease in the liquid temperature during melting of the solid is measured.
Answer:
When a heat body is mixed (or kept in contact) with a cold body, heat energy passes from the hot body to the cold body, till both the bodies attain the same temperature, if no energy is lost to the surroundings i.e., system is fully insulated.
Heat lost by hot body = Heat gained by cold body
It's other name is Principle of Calorimetry.
