In an isothermal process, 3700 J of work is done by an

Solution 3Q

Step 1 of 2

What is isothermal expansion. It is the expansion when the product of P(Pressure) and V(Volume) is equal to a constant. I.e PV = K ( a constant)

We do not know the pressure at which it was compressed from 1 litre to 0.5 ltre. So we can use p/P0. Where P0 is atmospheric pressure at sea level.

So if at the start pressure was P1 and volume is 1 litre. It is compressed to 0.5 litres at same pressure. It is now expanded. Initial Pressure = P1, Volume = 0.5 litres.

As PV = constant P1V1 = P2V2. It will expand to 1 litre. So 0.5 * P1 = 1* P2. So P2 = Twice the value of P1.
