- 5So each four dot shows four different states for an ideal gas. P is the pressure and the other one is the density of the gas. Is temperature of state 1 less or greater than the state 2? Can you please explain why?Experiment 1. The student measures the volume of the gas in the cylinder, places a known mass mon top of the piston, and then increases the temperature of the gas at constant pressure to 273C. Experiment 2. After the gas is allowed to cool back to 0C at 1 atm pressure, the student locks the piston in place, and then increases the temperature of the gas to 273C. Experiment 3. After Experiment 2 is completed, the student unlocks the piston, and a computer-controlled heat source maintains the temperature at a constant 273C. After Experiment 2, how do the pressure and volume change (increase/decrease/remain the same)? After Experiment 3?
- Complete the following statement: The absolute temperature of an ideal gas is directly proportional to O the average momentum of a molecule of the gas. O the amount of heat required to raise the temperature of the gas by 1 Cº. O the number of molecules in the sample. O the relative increase in volume of the gas for a temperature increase of 1 Cº. O the average kinetic energy of the gas.Problem #1: An ideal gas of initial volume V=1m^3, initial temperature T=1000C and initial pressure P=10,000 Pa is heated up to a final temperature T=3000C and allowed to expand into a final volume V=3m^3. What is the final pressure?If a (non-ideal) gas has non-negligible attractive intermolecular forces, would you expect the temperature to increase, decrease, or stay the same during an iso-enthalpic expansion of the gas? Explain your reasoning.
- 2.00 mol of helium and 1.00 mol of argon are separated by a very thin barrier. Initially the helium has 7500 J of thermal energy. The helium gains 2500 J of energy as the gases interact and come to thermal equilibrium by exchanging energy via collisions at the boundary. What was the initial temperature of the argon?
