Solution

Mass of iron m = 2.0 kg

Thermal Heat Capacity c' = 966 J/°C

Rise in temperature T = 15°C

We know that specific heat capacity is = `"heat capacity"/ "mass of substance"`
So specific heat capacity is = `966 / 2`

= 483 J kg-1 K-1

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.
