7. Gases

Using the ideal gas law, what is the pressure (in atm) of 1.9 mol of nitrogen gas in a 9.45 L tank at a temperature of 228 K? (Use R = 0.0821 L·atm·mol^{-1}·K^{-1})

Which of the following gases is not a greenhouse gas?

Which equation from the ideal gas law shows how the amount of gas in moles (n) is related to the temperature (T)?

Which of the following is the correct expression for Avogadro's Law, where k is a constant?

According to the ideal gas law, how do temperature and pressure affect the volume of a gas, assuming the amount of gas is constant?

Which process is primarily responsible for producing the oxygen we breathe?

The density of an ideal gas is directly proportional to which of the following quantities?

Under which of the following conditions will nitrogen (N_2) behave most like an ideal gas?

Under which of the following conditions are gases most likely to behave ideally?

Which equation represents the Ideal Gas Law?

An 80 g sample of oxygen gas (O_2) was heated from 25°C to 225°C at constant pressure. Using the ideal gas law, what happens to the volume of the gas?

Using the ideal gas law, what pressure (in atm) will be exerted by 1.5 moles of neon gas occupying 5.0 L at 273 K?

Why does the pressure inside a container of gas increase when more gas is added to the container, assuming volume and temperature remain constant?

A fixed container containing an ideal gas is heated. The pressure of the gas increases because:

A laser tube contains krypton gas (Kr) at 0°C and 1 atm pressure. If the volume of the tube is 22.4 L, approximately how many moles of Kr are present in the tube?
