Calculate the work invoved when when 1 mol of an ideal gas is compressed reversibly from `1.00` bar to `5.00` at a constant temperature of `300K` .

A

`-14.01KJ`

B

`+18.02KJ`

C

`4.01KJ`

D

`-8.02KJ`

Text Solution

Verified by Experts

The correct Answer is:
C
`w=-2.0303nRT` log `(P_(1))/(P_(2))`
so, `w=-2.303xx1xx8.314xx300` log `(1)/(5)`
`=-2.303xx8.314xx300` (log `1-log5`)
`=-5744.14xx(0-0.6990)`
`=4015.15J`
`=4.01KJ`

Calculate the work done when 1 mol of an ideal gas is compressed reversibly from 1 bar to 4 bar at a constant temperature of 300 K

The pressure-volume of varies thermodynamic process is shown in graphs: Work is the mole of transference of energy. It has been observed that reversible work done by the system is the maximum obtainable work. w_(rev) gt w_(irr) The works of isothermal and adiabatic processes are different from each other. w_("isothermal reversible") = 2.303 nRT log_(10) ((V_(2))/(V_(1))) = 2.303 nRT log_(10)((P_(2))/(P_(1))) w_("adiabatic reversible") = C_(V) (T_(1)-T_(2)) Calculate work done when 1 mole of an ideal gas is expanded reversibly form 30L to 60L at a constant temperature of 300k
