Two bolcks to the same metal having same mass and at temperature `T_1` and `T_2` respectively ,are brought in contact with each other and allowed to attain thermal equilibrium at constant pressure .The change in entropy ,`Delta S` for this process is :
Two bodies A and B are said to be in thermal equilibrium with each other if they have same
Two iron spheres of equal mass having temperatures 20^@C and 48^@C are brought into contact with each other. What is the equilibrium temperature? Assume there is no heat loss to surroundings.
A monoatomic gas of n-moles is heated temperature T_1 to T_2 under two different conditions (i) at constant volume and (ii) At constant pressure The change in internal energy of the gas is
Two vessels of volume (V_1) and (V_2) contain the same ideal gas. The pressures in the vessels are (P_1) and (P_2) and the temperatures are (T_1) and (T_2) respectively . The two vessels are now connected to each other through a narrow tube. Assuming thar no heat is exchanged between the surrounding and the vessels, find the common pressure and temperature attained after the connection.
Two bodies at different temperature T_(1) and T_(2) . If brought in thermal contact do not mecesserily settle to the mean temperature (T_(1)+T_(2))//2 .
The velocity of sound in an ideal gas at temperature T_1 and T_2 K are v_1 and v_2 respectively. If the root mean square velocity of the same gas at same temperature are c_1 and c_2 then-
