what is gas pressure affected by?
temperature, gas, and number of particles
what is pressure?
the result of a force distributed over an area.
what causes the pressure in a closed container of gas?
collisions between particles of a gas and the walls of a container
what effect does lowering the temperature of gas have on its pressure, if the volume of the gas and the number of its particles are kept constant?
it will decrease the pressure of gas
how does reducing the volume of a gas effect its pressure if the temperature if the gas and the number of particles are constant?
it increases the pressure if the temperature and the volume are constant
if you decrease the number of particles of a gas will _______ its pressure if the temperature ad the volume are constant.
decrease
a temperature equal to 0K on the Kelvin temperature scale if know as_________________
absolute zero
what does charles law state?
that the volume of a gas is directly proportional to its temperature in Kelvins if the pressure and the number if particles in a gas are constant.
what factors are included in the combined gas law?
temperature, volume, and pressure
if the temperature and number of particles of a gas in a cylinder do not change, and the volume of the cylinder is reduced by half, the pressure of the gas will be _________ as the original pressure.
doubled
how do you find pressure?
force/surface area
what is boyles law?
at constant temperature when volume increases/decreases pressure increases/decreases
- varies inversely: the variables do the opposite
what is charles law?
constant pressure, when the temperature increases/decreases, volume increases/decreases
what is directly proportional?
when both variables increase at the same rate
what is a rigid container?
at a constant volume, when temperature increases/decreases, pressure increases/decreases
what two laws can you combine together?
charles law and rigid container
