A sample of gas occupies a volume of 1.0 L at 25°C and constant pressure. What volume will the gas occupy at 100°C, assuming ideal gas behavior?

A 5.00 L tank contains 10.00 grams of oxygen gas (O_2) at a temperature of 350 K. What is the pressure in the tank in atmospheres (atm)? (Use R = 0.0821 L·atm·mol^{-1}·K^{-1})

Which of the following factors directly affect the behavior of the gas inside a hot air balloon according to the ideal gas law?

A 6.00 L tank contains 20.0 grams of nitrogen gas (N_2) at a temperature of 385 K. What is the pressure inside the tank? (Use R = 0.0821 L·atm·mol^{-1}·K^{-1})

A sample of gas occupies 100 in^3 at a pressure of 20 psi and a constant temperature. According to the ideal gas law, what would the volume of the gas be if the pressure is increased to 40 psi?

A sample of gas is collected over water at atmospheric pressure (patm = 1.00 atm). If the vapor pressure of water at the experimental temperature is 0.030 atm, what is the pressure of the dry gas (pgas)?

Under which conditions do gases behave most ideally?

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?
