1.

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 DeltaE (Given 1 L atm = 101 J)

Answer»

`{:("Q","W",DELTA"E"),("250J","-455J","-205J"):}`
`{:("q","w",Delta"E"),("-250J","-455J","-710J"):}`
`{:("q","w",Delta"E"),("250J","455J","710J"):}`
`{:("q","w",Delta"E"),("-250J","455J","205J"):}`
