THERE ARE 2 QUESTIONS. Question 1: An ideal gas at temperature T0 is slowly compressed at constant pressure of 2 atm from a volume of 10 liters to a volume of 2 liters. Then the volume of the gas is held constant while heat is added, raising the gas temperature back to T0. Calculate the work done ON the gas. 1 atm = 1.0×10^5 Pascals and 1 liter = 0.001 m^3 ANSWER CHOICES: 1. +400 J 2. −1600 J 3. +1600 J 4. +800 J 5. −800 J 6. −400 J QUESTION 2: Calculate the heat flow INTO the gas 1. −1600 J 2. −800 J 3. −400 J 4. +1600 J 5. +400 J 6. +800 J
