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 the energy needed for evaporation is taken from the water itself and the water is cooled down. Assume that a pitcher contains 10kg water and 0.2g of water comes out per second. Assuming no backward heat transfer from the atmosphere to the water, calculate the time in which the temperature decreases by 5^(@)C . Specific heat capacity of water = 4200J kg^(-1).^@C^(-1) and latent heat of vaporization of water = 2.27 xx 10^(6)J kg^(-1)

Find the increase in mass when 1 kg of water is heated from 0^@C to 100^@C . Specific heat capacity of water = 4200 J kg^(-1) K^(-1) .

Find the increase in mass when 1 kg of water is heated from 0^@C to 100^@C . Specific heat capacity of water = 4200 J kg^(-1) K^(-1) .

Calculate the increase in the internal energy of 10 g of water when it is heated from 0^(0)C to 100^(0)C and converted into steam at 100 kPa. The density of steam =0.6 kg m^(-3) specific heat capacity of water =4200 J kg^(-1 ^(0)C^(-3) latent heat of vaporization of water =2.25xx10^(6) J kg^(-1)

Calculate the increase in the internal energy of 10 g of water when it is heated from 0^(0)C to 100^(0)C and converted into steam at 100 kPa. The density of steam =0.6 kg m^(-3) specific heat capacity of water =4200 J kg^(-1 ^(0)C^(-3) latent heat of vaporization of water =2.25xx10^(6) J kg^(-1)

Calculate the increase in the internal energy of 10 g of water when it is heated from 0^(0)C to 100^(0)C and converted into steam at 100 kPa. The density of steam =0.6 kg m^(-3) specific heat capacity of water =4200 J kg^(-1 ^(0)C^(-3) latent heat of vaporization of water =2.25xx10 6 J kg^(-1)

Calculate the heat energy required to raise the temperature of 2 kg of water from 10^@ C to 50^@ C. Specific heat capacity of water is 4200 J kg^(-1) K^(-1) .

Explain why does drinking water kept in an earthern pot cool down ?

A waterfall whose vertical height is 100m discharges water into a pool below the fall. Calculate the rise in temperature of water assuming that all the heat remains in the water. (Specific heat capacity of water =4200J kg^(-1)K^(-1) )
