A gas is allowed to expand at constant pressure from a volume of 1.0 litre to 10.0 litre against an external pressure of 0.50 atm. If the gas absorbs 250 J of heat from the surroundings, what are the values of q, w and `Delta E`. (Given : 1 L atm = 101 J)

A

`|{:(q,w,DeltaE),(250J,-460J,-210J):}|`

B

`|{:(q,w,DeltaE),(-250J,-460J,-710J):}|`

C

`|{:(q,w,DeltaE),(250,460,710J):}|`
