Which statement about the volume and pressure of a gas is MOST accurate?

• Volume of a gas is equal to pressure of that gas in any container?

• Volume of a gas is always greater than pressure of that gas in any container.

• Volume of a gas is directly proportional to pressure of that gas in any container

• Volume of a gas is inversely proportional to pressure of that gas in any container.

Which statement BEST describes air pressure at high altitudes?

• Air pressure decreases as altitude increases

• Air pressure increases as altitude increases

• Air pressure does not change as altitude increases

• It is impossible to accurately measure air pressure at high altitudes.

What happens to pressure if temperature increases?
