Question 26

Multiple Choice

A gas is allowed to expand, at constant temperature, from a volume of 1.0 L to 10.1 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, w, and Δ\Delta E               q              w              ΔE~~~~~~~~~~~~~~\underline{q}~~~~~~~~~~~~~~\underline{w}~~~~~~~~~~~~~~\underline{\Delta{E}}
