An 8-l cylinder contains air at 300 kpa and 300 k. now air is compressed isothermally to a volume of 2 l. the work done on air during this compression process is: (b) 1.8 kj (c) 3.3 kj (a) 119 kj (d) 4.5 kj

W=3.327 KJ

Explanation:

Given that

Temperature remains constant it means that this is isothermal process

For isothermal process

We know that work for isothermal process  

Now by putting the values

W=-3.327 KJ

Negative sign indicates is process is compression

W=3.327 KJ

So our option C is right.
