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 ΔU? (Please Explain.)
A. Q = 250 J; W = -460 J; ΔU = -210 J
B. Q = -250 J; W = -460 J; ΔU = -710 J
C. Q = 250 J; W = 460 J; ΔU = 710 J
D. Q = -250 J; W = 460 J; ΔU = 245 J
E. Q = 250 J; W = -4.55 J; ΔU = 245 J
