How much work (in J) is required to expand the volume of a pump from 0.0 L to 2.5 L against an external pressure of 1.1 atm? Express your answer using two significant figures.
A gas is allowed to expand from a volume of 4.5 L to a volume of 6.39 L against a constant external pressure of 1.00 atm. How much PV work (in joules) is performed on the surroundings? Express your answer to two decimal places. (1 L·atm = 101.3 J)
Calculate the work done (in joules) by a chemical reaction if the volume increases from 3.2 L to 3.4 L against a constant external pressure of 3.5 atm . Express your answer with two significant figures. I calculated it myself and got 80 J as an answer but it is saying that is incorrect. PLEASE HELP! thanks!
