The calorimeter ideal insulation in three situations

Calorimeters In ideal insulation, there is no heat exchange between the measurement system and the environment.

The following three conditions meet this requirement as much as possible:

1) The sample is reflected so fast that the amount of heat that escapes from the system at the measurement interval or enters the system from the environment is so small that it cannot be measured.

2) The measurement system is isolated from the environment by an infinite thermal resistance.

3) Control the temperature of the environment so that it is always consistent with the temperature of the measurement system.
