According to law of calorimetry, which of the given relation is true?

A) Heat gained = Heat lost

B) There is no change in heat

C) There is only heat gain

D) There is only heat loss

The correct option is A) Heat gained = Heat lost

According to the law of calorimetry, Heat gained = Heat lost

According to the law of calorimetry or principle of calorimetry states that if there is no heat loss in the surrounding, then the heat lost by the body is equal to the heat gained by the body.

Following is the formula which is used for calculating the heat transfer in a system:
q = mcΔt
Where,

  • q is the measure of heat transfer
  • m is the mass of the body
  • c is the specific heat of the body
  • Δt is the change in temperature
