Question 3 1 pts The volume of a gas (which is not necessariiy monatomic g diatomic) increases by a factor of 4.5 during an adiabatic expansion. This decreases the pressure by a factor of 6.7. By what factor does the temperature change? Round your answer to 2 decimal places i.e., #.##. Question 4 1 pts 0.25 moles of iodine in its gas phase is at a pressure of 7.5 atm. How much heat is required to raise the temperature of this gas by 90 F at constant pressure? 0 1701 0 None of these. 0 1001 O 12J O J O 20J Question 5 1 pts 0.25 moles of iodine in its gas phase is at a pressure of 1.1 kPa. How much work is done by the gas when its volume becomes one-third of its initial value at a temperature of 350 K? O 370J O 550J O 550J O 800J Q 800J 0 None of these. 0 370J
