Question

Two metals A and B have specific heat capacities in the ratio 2:3. If they are supplied same amount of heat then

If specific heat capacity of metal A is 0.26 Jg-1 0C-1 then calculate the specific heat capacity of metal B.

Numerical

Solution

It is given that, ratio of specific heat capacities, `"C"_"A"/"C"_"B" = 2/3` and `"C"_"A" = 0.26`

Calculating we get, CB = 1.5 × 0.26 = 0.39.

Therefore, specific heat capacity of metal B is 0.39 Jg-1°C-1.

Which principle is used to measure the specific heat capacity of a substance?


Indian style of cooling drinking water is to keep it in a pitcher having porous walls. Water comes to the outer surface very slowly and evaporates. Most of energy needed for evaporation is taken from the water itself and the water is cooled down. Assume that a pitcher contains 10 kg of water and 0.2 g of water comes out per second. Assuming no backward heat transfer from the atmosphere to the water, calculate the time in which the temperature decrease by 5°C. Specific heat capacity of water = 4200 J kg−1 °C−1 and latent heat of vaporization of water = 2.27 × 106 J kg−1.
