Certain amount of a non-ideal gas is changed from state (500 K, 5 atm, 2 L) to (150 K, 2 atm, 1L). If the change in internal energy is 14 L-atm, change in enthalpy in L-atm unit is

One mole of an ideal gas undergoes change of state from (4 L, 3 atm) to (6 L, 5 atm). If the change in internal energy is 45 L-atm then the change of enthalpy for the process is

One mole of an ideal gas undergoes a change of state (2.0) atm, 3.0 L) to (2.0 atm, 7.0 L) with a change in internal energy (DeltaU) = 30 L-atm. The change in enthalpy (DeltaH) of the process in L-atm :

One mole of non - ideal gas undergoes a change of state (1.0 atm, 3.0L, 200 K ) to (4.0 atm, 5.0L,250 K) with a change in internal energy (DeltaU)=40 L-atm . The change in enthalpy of the process in L-atm ,

One mole of a non-ideal gas undergoes a change of state ( 2.0 atm, 3.0L, 95 K) rarr (4.0 atm, 5.0L, 245 K) with a change in internal energy , Delta U= 30.0 L. atm . Calculate change in enthalpy of the process in L. atm .

A system containing real gas changes it's state from state -1 to state - 2 . State -1 ( 2atm, 3L,300K) State-2 (5 atm, 4L,500K) If change in internal energy = 30 L atm then calculate change in enthalpy.

When a sample of ideal gas is changed from an initial state to a final state, various curves can be plotted for the process like P-V curve, V-T curve,P-T curve etc. For example, P-V curve for a fixed amount of an ideal gas at constant temperature is a rectangular hyperbola, V-T curve for a fixed amount of an ideal gas at constant volume is again a straight line. However, the shapes may vary if the constant parameters are also changed. Now, answer the following questions : Two moles of an ideal gas is changed from its initial state (16 atm, 6L) to final state (4 atm, 15L) in such a way that this change can be represented by a straight line in P-V curve.The maximum temperature attained by the gas during the above change is :(Take : R=1/12L atm K^(-1) "mol"^(-1) )

1 mol of a gas is changed from its initial state (15 L, 2 atm) to final state (4 L, 10 atm) . If this change can be represented by a straight line in P-V curve, calculate the maximum temperature that, the gas attained.

A gas expends from 2 L to 6L against a constant pressure of 0.5 atm on absobing 200 J of heat. Calculate the change in internal energy.
