2 cards from this section. Quick, good the night before a test.
What is the equation relating pressure to molecular speed and density?
Remember, n is the number density.
Define what is meant by an elastic collision.
Think about energy before and after the collision.
What is pressure in a gas a result of?
Think about what molecules do inside the container.
True or False: The average kinetic energy of gas molecules increases with increasing temperature.
Remember the relationship between temperature and energy.
A cylinder contains nitrogen gas at a pressure of 2 atm and a temperature of 300 K. Calculate the volume of the gas in liters if there are 0.5 moles of nitrogen.
Remember to convert pressure to standard units if needed.
If the density of a gas is increased while temperature remains constant, how does that affect the pressure? Provide reasoning.
Refer to the formula P = nRT/V and consider how n (number density) behaves.
