air pressure correct answersforce air exerts on a surface, divided by the area of a surface Force/Area true or false Air pressure has the same value in all directions correct answerstrue if the volume of a container of gas decreased, what would happen to the value of the gas pressure correct answersit would increase density correct answersamount of matter/volume the pressure in a gas depends on three quantities correct answersVolume, temperature, and amount of gas gas properties relationship correct answerspressure - amount of gas x temperature/volume What would happen to the volume of the pressure if two changes were made to nitrogen gas, one after the other? First the volume of the container is doubled (constant temp) second the temp is doubled (volume no longer changing) The amount of gas remains constant through both processes correct answersThe value of the pressure would end up the same (use the Gas properties relationship equation) An atom, molecule as a single small... correct answersparticle How many particles do you think would fit end to end in the width of your finger? correct answers100 million Gases correct answersParticles are far apart move in all directions change direction when they pump into each other no attraction to each other nothing between the particles particles move at constant speed in straight line a collection of gas particles has an average speed, with some particles moving faster and some moving slower than the average speed gas particles are much smaller then the space between them
