The Sun having radius R and surface temperature T , emits radiation as a perfect emitter. The distance of the earth from the sun is r and the radius of the earth is R_ e . The totaGraphs (drawn with the same scale) showing the variation of pressure with volume for a certain gas undergoing four different cyclic processes , B , C and D are given below. The cycThe molar specific heat of an ideal gas in a certain thermodynamic process is T where is a constant. If the adiabatic exponent is = C_P C_V , the work done in heating the gas from Under standard conditions of temperature and pressure a piece of ice melts completely on heating it.
