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`)

A

`"+250 J -455 J -205 J"`

B

`"-250J -455J -710 J"`

C

`"+250 J +455J +710 J"`

D

`"-250 J +455 J +205 J"`
