प्रश्न
State two factors upon which the heat absorbed by a body depends.
Advertisements
उत्तर
- Mass of the body: Greater the mass, greater is the heat absorbed.
- Rise in temperature: Greater the rise in temperature, greater is the heat absorbed.
- Nature of the substance (specific heat capacity): Higher the specific heat capacity, greater is the heat absorbed.

In an experiment on the specific heat of a metal, a 0.20 kg block of the metal at 150 °C is dropped in a copper calorimeter (of water equivalent 0.025 kg) containing 150 cm3 of water at 27 °C. The final temperature is 40 °C. Compute the specific heat of the metal. If heat losses to the surroundings are not negligible, is your answer greater or smaller than the actual value for the specific heat of the metal?
