A gas is allowed to expand at constant temperature from a volume of `1.0 L` to `10.0 L` 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` and `DeltaE` ? (Given `1 L "atm" =101 J`)

Options

A. `|{:(q,w,DeltaE),(250J,-460J,-210J):}|`
B. `|{:(q,w,DeltaE),(-250J,-460J,-710J):}|`
C. `|{:(q,w,DeltaE),(250,460,710J):}|`
D. `|{:(q,w,DeltaE),(-250,460J,210J):}|`

Answer

A
