Starting with 2.70 mol of N2 gas (assumed to be ideal) in a cylinder at 1.00 atm and 15.0 ∘C, a chemist first heats the gas at constant volume, adding 1.36 × 104 J of heat, then continues heating and allows the gas to expand at constant pressure to twice its original volume. (a) Calculate the final temperature of the gas (b) Calculate the amount of work done by the gas. (c) Calculate the amount of heat added to the...
Under constant-volume conditions, 3100 J of heat is added to 1.9 moles of an ideal gas....
Under constant-volume conditions, 3100 J of heat is added to 1.9 moles of an ideal gas. As a result, the temperature of the gas increases by 78.5 K. How much heat would be required to cause the same temperature change under constant-pressure conditions? Do not assume anything about whether the gas is monatomic, diatomic, etc.

Under constant-volume conditions, 4100 J of heat is added to 1.5 moles of an ideal gas. As a result, the temperature of the gas increases by 132 K. How much heat would be required to cause the same temperature change under constant-pressure conditions? Do not assume anything about whether the gas is monatomic, diatomic, etc.

A balloon containing 4.00 moles of N2 gas has a volume of 0.750 L at a pressure of 1.00 atm and a temperature of 27°C. What will the new volume of the balloon be, in liters, if the pressure is doubled to 2.00 atm, the temperature is increased to 127°C, and 1.50 moles of N2 is removed from the balloon? On an airliner, an inflated toy has a volume of 0.310 L at 25°C and 745 mmHg. During flight, the...

A tank with a constant volume of 5.89 m3 contains 15 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 56500 J of energy into the gas. It may help you to recall that CVCV = 12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas....

A balloon filled with 35.6 moles of helium has a volume of 856 L at 0.0°C and 1.00 atm pressure. The temperature of the balloon is increased to 43.0°C as it expands to a volume of 967 L, the pressure remaining constant. Calculate q, w, and ΔE for the helium in the balloon. (Given, the molar heat capacity for helium gas is 20.8 J/°C · mol, and 1 L·atm = 101.3 J) (Show your work)
