Option 1 : The temperature of the two bodies are same even if their heat contents are different.

Explanation:

On checking options :

  • Option 1) Heat content of two bodies also depends on their masses and specific heat capacities (mass × specific heat capacity = heat capacity). 
    • Suppose two bodies of different heat capacities were at the same temperature initially. Now if the same heat is given to both of them, the body with lower heat capacity will have a higher temperature. So, if two bodies have the same heat content, it doesn't necessarily mean they have the same temperature.     FALSE
  • Option 2) Heat is measured by the principle of calorimetry.     TRUE
  • Option 3) Heat content of a body depends upon its mass, temperature, and also on its specific heat capacity.    TRUE
  • Option 4) On mixing two bodies, total heat content is equal to the sum of the heat content of each body provided heat is not lost to surroundings during the process.   TRUE
