A geyser heats water flowing at the rate of 3.0 litres per minute from 27^(@)C to 77^(@)C . If the geyser operate on a gas burner, what is the rate of consumption of the fuel if its heat of combustion is 4.0 xx 10^(4) J/g ?

A child running a temperature of 101 ^(@) F is given an antipyrin (1.e. a medicine that lowers fever) which causes an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^(@) F in 20 minutes, what is the average rate of extra evaporation caused by the drug. Assume the evaporation mechanism to be the only way by which heat is lost. The mass of the child is 30 kg The specific heat of human body is approximately the same as that of water, and latent heat of evaporation of water at that temperature is about 580 " cal g"^(-1) .

    A 0.60 kg sample of water ans a sample of ice are placed in two compartments A and B that are separated by a conducting wall in a thermally insulated container. The rate of heat transfer from the water to the ice through the conducting wall is constant P, until thermal equilibrium is reached. The temperatures T of the liquid water and the ice are given in graph as functions of time t. Temperatures of the compartments remain homogeneous during the whole heat transfer process. Given, specific heat of ice = 2100 J/kg-K Specific heat of water = 4200 J/kg-K latent heat of fusion of ice = 3.3 xx 10^(-5) J/kg The value of rate P is
