There is a temperature difference of `1K` between two black patches of skin on patient's chest and each patch having area A The radiant heat emitted from them is differ by `2%` then temperature of two patches may be .

Heat is the transfer of energy between two objects with different temperature.

The rates of heat radiation from two patches of skin each of area A on a patient's chest differ by 2% If the patch of the lower temp is at 300K and emissivity of both the patches is assumed to be unity, the temp of other patch would be .

Two bodies A and B having equal outer surface areas have thermal emissivity 0.04 and 0.64 respectively. They emit total radiant power at the same rate. The difference between wavelength corresponding to maximum spectral radiance in the radiation from B and that from A is 2 mum . If the temperature of A is 6000 K, then

When two samples of finite specific heats at different temperatures are mixed the temperature of the mixture may be:

Two cylindrical rods of same meterial have the same temperature difference between their ends. The ratio of rates of flow of heat through them is 1 : 8. The ratio of the radii of the rods are 1 : 2. What is the ratio of their lengths ?

The rate of heat radiation from two patches of skin each of area S, on a patient's chest differ by 2%. If the patch of the lower temperature is at 300 K and the emissivity of both the patches is assumed to be unity, the temperature of the other patch is closest to

Two cylindrical rods of the same material have the same temperature difference between their ends. The ratio of the rates of flow of heat through them is 1 : 8. The radii of the rods are in the ratio 1 : 2. What is the ratio of their lengths ?
