True or false? Gas pressure is caused by molecules in a gas colliding with the walls of their container.

True or false? Each gas in the air has a different boiling point.truefalse

Gas pressure in a closed system is caused by:heat given off by constant collisionsresultant force of all collisions with the container walls.compression of the gasrapid diffusion of gas through the systemSUBMIT ANSWER

Select all that applyWhich of the following statements correctly describe gas pressure? Select all that apply.Multiple select question.Pressure is caused by gas particles striking the walls of the container.Only gases in containers exert pressure on objects.Shrinking the container surface area will lower the pressure inside.Adding more gas to a container will increase the pressure inside.

Which statements about gases are true?They don't change in volumeThey are fluids that change shape depending on their containerThey tend to fill the entire space of their containerThey change volume depending on their containerI'm not sure

A given amount of gas is held inside a container.  The volume of the container can be changed using a movable piston.  Which of the following will cause the pressure which the gas exerts on the walls of the container to decrease?Pushing the piston inwards (so that the volume of the container decreases)Heating the gasPulling the piston outwards (so that the volume of the container increases)Pumping more gas into (increasing the number of particles inside) the container
