7. Gases

Under which of the following conditions would a gas that typically behaves non-ideally be made to act more like an ideal gas?

Which of the following gases will absorb in the IR spectrum?

If both the pressure and volume of an ideal gas are increased, what will happen to the temperature, assuming the amount of gas remains constant?

What is the volume, in liters, of 15 moles of CO_2 gas at 50 °C and 800 torr? (Use R = 0.0821 L·atm·mol^{-1}·K^{-1})

Under which conditions do real gases behave most like ideal gases?

Which of the following gases behaves most like an ideal gas under standard conditions?

In an experiment using the ideal gas law, what is a likely consequence if the gas flow rate is set too high?

Which of the following statements about the application of the Ideal Gas Law to the atmospheres of the outer planets is correct?

45.4 liters of hydrogen are collected over water at 76.0°C and has a pressure of 498 torr. What would the pressure (in torr) of the 'dry' hydrogen at 22.2°C in an 11.6 liter container be? (Water Vapor Pressure at 76.0°C is 301.4 torr)

Which of the following best explains why the pressure of a sample of gas at constant volume could decrease by 75 mm Hg?

A sample of argon gas has a volume of 735 mL at a pressure of 1.20 atm and a temperature of 112°C. What is the final volume of the gas, in milliliters, when the pressure is changed to 0.85 atm and the temperature is changed to 25°C, assuming the amount of gas remains constant?

Using the ideal gas law, what is the temperature in degrees Celsius of 5.20 moles of gas in a 40.0 L container at a pressure of 4.50 atm?

A gas occupies a volume of 0.77 L at 20°C and 720 torr. Using the Ideal Gas Law, what volume would the gas occupy at 48°C and 760 torr?

Using the Ideal Gas Law, what is the pressure exerted by a 75.0 g sample of dinitrogen monoxide (N2O) gas in a 4.21 L vessel at 298 K?

An unknown gas has a mass of 1.56 g, a volume of 0.50 L, a temperature of 315 K, and a pressure of 1.14 atm. Using the Ideal Gas Law, identify the gas.
