Consider a black body radiation in a cubical box at absolute temperature T. If the lengh of each side of the box is doubled and the temperature of the walls of the box and that of the radiation is halved then the total energy

The volume of a cubical box is 474.552 cubic metres. Find the length of each side of the box.

If the absolute temperature of a black body is doubled the percentage increase in the rate of loss of heat by radiation is .

A black body radiates at the of W watts at a temperture T. If the temperature of the body is reduced to T//3 , it will radiate at the rate of (in Watts)

n molecules of an ideal gas are enclosed in cubical box at temperature T and pressure P. If the number of molecules in the box is trippled then new temperature and pressure become T' and P respectively. But the total energy of gas system remanins unchangted, then-

ow energy density in black body radiation depends upon temperature?

A black body at a high temperature T radiates energy at the rate of E. When the temperature falls to T/2,the radiated energy will be

A container has N molecules at absolute temperature T. If the number of molecules is doubled but kinetic energy in box remains the same as before, the absolute temperature of the gas is
