A certain mass of a gas is compressed first adiabatically, and then isothermally. In both cases, the initial state of the gas is the same. Is the work done `W_(1)` in the first case greater than the work done `W_(2)` in the second case ? Explain.

A gas is first compressed adiabatically and then isothermally. In both cases, the initial state of the gas is the same. Find in which case more work is done on the gas.

A certain mass of nitrogen was compressed eta = 5.0 times (in terms of volume), first adiabatically, and then isothermally. In both cases the initial state of the gas was the same. Find the ratio of the respective works expended in each compression.

A spring, which is initially in its unstretched condition, is first stretched by a length x and then again by a further length x. The work done in the first case is W_(1) and in the second case is W_(2) .

A spring, which is initially in its unstretched condition, is first stretched by a length x and then again by a further length x. The work done in the first case is W_(1) and in the second case is W_(2) .

1 mol of an ideal gas is compressed to half of its initial volume (i) isothermally and (ii) adiabatically. Draw the p-V diagram in each case and hence state with reason, in which case the work done in less.

A spring which is initially in un-streatched condition, is first stretched by a length x and again by a further length x. The work done in the first case W_(1) is one third of the work done in second case W_(2) . True of false ?
