10 moles of an ideal gas expands isothermally and reversibly from a pressure of 10 atm to 2 atm at 300K. What is the largest mass that can be lifted through a height of 1m in this expansion?

Work done in an isothermal reversible process is always ________than the work done in an isothermal irreversible process.

One mole of an ideal gas expands against a constant external pressure of 1 atm from a volume of 10L to 30L. Calculate the work done by the gas in Latm.

J-T effect is an________process

$$\Delta H\degree=?$$  

$$\Delta H\degree=?$$  (KJ/mol)

The rection shown in the graph is an example of

A given mass of a gas at 0 degree C is compressed reversibly and adiabatically to a pressure 20 times its initial value. Calculate final temperature of gas in degree C. $$\gamma=1.42\ for\ the\ gas$$
