7. Gases

Under which conditions do gases behave most ideally?

A 5.00 L tank contains 2.50 moles of oxygen gas at 39.3 °C. What is the pressure in atm inside the tank? (R = 0.0821 L·atm·mol^{-1}·K^{-1})

Which of the following scenarios would result in work being done by an ideal gas on its surroundings?

Which of the following changes will cause the volume of an ideal gas to triple, assuming the amount of gas and pressure remain constant?

Which of the following compounds will behave least like an ideal gas at low temperatures?

How does increasing the temperature affect how closely a real gas behaves like an ideal gas?

A student collects a gas over water in a closed container. The atmospheric pressure is patmos = 1.00 atm, and the vapor pressure of water at the experimental temperature is 0.030 atm. What is the pressure of the dry gas (pgas) in the container?

A balloon contains 2.0 mol of an ideal gas at a pressure of 1.0 atm and a temperature of 273 K. What volume will the balloon occupy?

Which of the following actions will increase the pressure of a gas in a sealed container, according to the ideal gas law?

Which of the following occurs when a rigid container of gas is heated, assuming the amount of gas remains constant?

A 2 L container will hold about 4 g of which of the following gases at 0°C and 1 atm?

Under which conditions do real gases most closely resemble ideal gases?

What is the volume occupied by 51.0 g of ammonia (NH_3) gas at standard temperature and pressure (STP)?

At which of the following conditions will a sample of neon gas behave most like an ideal gas?

If 10 L of O_2 at 273 K and 1 atm is compressed to a 7 L container at 250 K, what will be the final pressure of the gas (in atm), assuming ideal gas behavior?
