Same amount of heat is added to two substances of same mass having specific heat capacities s1 & s2 such that s1 > s2. Select the correct statement.

Both will have the same change in temperature

The change in temperature of 1 is greater than the change in temperature of 2

The change in temperature of 1 is less than the change in temperature of 2

Both will have the same change in temperature

Temperature changes can t be related with specific heat capacities

What is the definition of 1 calorie?

It is the heat required to raise the temperature of 1g of any substance by 14.5 C to 15.5 C at 760mm Hg

It is the heat required to raise the temperature of 1g of water from 14.5 C to 15.5 C at 760mm Hg

It is the heat required to raise the temperature of 1g of any substance by 14.5 C to 15.5 C at 760mm Hg

It is the heat required to raise temperature of 1g of water by 1 C at 760mm Hg

It corresponds to the heat supplied at 760mm Hg for 1 C raise in temperature

What is the principle of a calorimeter?

Heat loss depends only on specific heat of a substance

Heat loss rate is directly proportional to temperature difference

The total heat lost by a hot body is same as the total heat gained by the cold body provided no heat is lost to the surroundings

Heat loss depends only on specific heat of a substance

For the same amount of heat flow from a sample to two different samples of same mass is a product of their specific heats and temperature difference
