#1 The internal energy of the gas in a gasoline engine’s cylinder decreases by 295 J. If 47.0 J of
work is done by the gas, how much energy is transferred as heat?
#2 If an ideal gas does work on its surroundings:
a. The internal energy of the gas increases
b. The volume of the gas decreases
c. The volume of the gas increases
d. The pressure of the gas increases
Btw , This Is Not Homework This Is A Study Guide For The Final Exam.

#1 change in U = Qin  Wout
295 = Qin 47
Qin = 248 J, which means that 248 J heat was trasfered OUT.
#2. Work done by a gas = P*(increase in V)
What does that tell you?
Is that your last question for today or forever?
