Assertion (A): In human male, testes are extra abdominal which are present inside scrotum. Reason (R) : Scrotum has a relatively lower temperature needed for the production and storage of sperms.

Two bodies of same shape, same size and same radiating power have emissivities 0.2 and 0.8. The ratio of their temperatures is

Two bodies of same shape, same size and same radiating power have emissivities 0.2 and 0.4 The ratio of their temperature is .

Newton’s law of cooling says that the rate of cooling of a body is proportional to the temperature difference between the body and its surrounding when the difference in temperature is small. (a) Will it be reasonable to assume that the rate of heating of a body is proportional to temperature difference between the surrounding and the body (for small difference in temperature) when the body is placed in a surrounding having higher temperature than the body? (b) Assuming that our assumption made in (a) is correct estimate the time required for a cup of cold coffee to gain temperature from 10^(@)C to 15^(@)C when it is kept in a room having temperature 25^(@)C . It was observed that the temperature of the cup increases from 5^(@)C to 10^(@)C in 4 min

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) .
