Question

If pressure is expressed in atmospheres and volume is expressed in liters, PΔV has units of L atm (liters × atmospheres). Remember that 1 atm = 101,325 Pa, and that 1 L = 1 dm³. Use this information to determine the number of joules corresponding to 2 L atm.

Answer 1

$J=Pa (m^3)=1000 Pa(l)=1000/101325 atm(l)=0.0099 atm(l)$

2 L atm=2/0.0099=202 J
