A sealed, rigid container is filled with three ideal gases: A, B, and C. How would you find the total pressure of the gases?

• Use Boyle's Law (P1V1=P2V2)

• Multiply the partial Pressures (AxBxC)

• Add together the partial pressure (A+B+C)

• Force/Area

You are about to go scuba diving and your tank is filled with 3 gases. The partial pressure of O2 is 0.93 atm, for N2 it’s 0.12 atm, and for CO2 it is 0.67 atm. What is the total pressure in the tank?

What happens to the pressure of a gas if the volume is decreased?

• It increases because it is a direct relationship

• It increases because it is an indirect relationship

• It decreases because it is a direct relationship

• It decreases because it is an indirect relationship

A gas occupies 13.4 L at 1.860 atm. What is the pressure if the volume becomes 10.0 L?

What happens to the volume of a gas if the temperature is increased?

• It decreases because it is a direct relationship

• It increases because it is an indirect relationship

• It decreases because it is an indirect relationship

• It increases because it is a direct relationship

A helium filled balloon has a volume of 44.0 L at 25°C and 1.06 atm. With a volume of 10.35 L and 0.575 atm what is the temperature in K?
