A child running a temperature if 101^(@)F is given an antipyrine (i.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 min, 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 water, and latent heat of evaporation of water at that temperature is about "580 cal g"^(-1) .

What is the specific heat of a gas in an a adiabatic process ?

An ice cube of mass 0.1 kg at 0^@C is placed in an isolated container which is at 227^@C . The specific heat s of the container varies with temperature T according to the empirical relation s=A+BT , where A= 100 cal//kg.K and B = 2xx 10^-2 cal//kg.K^2 . If the final temperature of the container is 27^@C , determine the mass of the container. (Latent heat of fusion for water = 8xx 10^4 cal//kg , specific heat of water =10^3 cal//kg.K ).
