Sahay Sir > Question Answers > calculate the initial rate of rise of temperature of the sphere The sphere may be treated as a black body rho_(copper) =8.93xx 10^(3)kg//m^(3) s = 3.7xx10^(2) Jkg^(-2) K^(-1)
Two identical containers A and B with frictionless pistons contain the ideal gas at the same temperature and the same volume V. The mass of the gas in A is m A and in B is m B . The gas in each cylinder is now allowed to expand isothermally to the same final volume 2V. The changes in pressure in A and B are found to be Δp and 1.5ΔP respectively. Then:

calculate the initial rate of rise of temperature of the sphere The sphere may be treated as a black body rho_(copper) =8.93xx 10^(3)kg//m^(3) s = 3.7xx10^(2) Jkg^(-2) K^(-1) ,
sigma = 5.7 xx 10^(8) Wm^(-2) K^(-4) . ,
solid copper sphere of dimater 10mm is cooled to temperature of 150K and is then placed in an enclousure at 290K Assuming that all interchange of heat is by radiation ,
Two cylinders A and B fitted with pistons contain equal amounts of an ideal diatomic gas at 300K. Piston of A is free to move and piston of B is fixed. Same amount of heat is given to the gases in two cylinders. Temperature of the gas in cylinder A increases by 30K. Then, increase in temperature of the gas in the cylinder B is: (γ=1.4 for diatomic gas)
