1) If 62.9 L of oxygen at 18.0°C and an absolute pressure of 2.28 atm are compressed to 56.5 L and at the same time the temperature is raised to 50.0°C, what will the new pressure be?
2) What is the average translational kinetic energy of a nitrogen molecule at STP?
What is the total translational kinetic energy of 1.90 mol of the N2 molecules at 20°C?
