A cylinder of radius and thermal conductivity is surrounded by a cylindrical shell of linear radius and outer radius, whose thermal conductivity is There is no loss of heat across cylindrical surfaces, when the ends of the combined system are maintained at temperatures . The effective thermal conductivity of the system, in the steady state is
The figure shows the volume versus temperature graphs for a certain mass of a perfect gas at two constant pressures of and What inference can you draw from the graphs
A volume and pressure diagram was obtained from state 1 to state 2 when a given mass of a gas is subjected to temperature changes. During this process the gas is
