Pressure versus temperature graph of an ideal gas at constant volume V is shown by the straight line A. Now mass of the gas is doubled and volume is halved, then the corresponding pressure versus temperature graph will be shown by the line. Pressure versus temperature graph of an ideal gas at constant volume V [...]

Gas at a pressure P0 is contained in a vessel . If the masses of all the molecules are halved and their speeds doubled, the resulting pressure would be Gas at a pressure P0 is contained in a vessel . If the masses of all the molecules are halved and their speeds doubled the resulting [...]

Rate of heat flow through two conducting rods of identical dimensions having thermal conductivities K_(1) and K_(2) and Q_(1) and Q_(2) when their ends are maintained at the same difference of temperature individually. When the two rods are joined in series with their ends maintained at the same temperature difference (as shown in the figure), [...]
