ideal gas molecules

why do gas particles create pressure

because when gas molecules collide with the walls of the container, each collision will exert a force on that wall which is called pressure.

what is absolute zero

absolute zero is the lowest possible temperature

-273 degrees

waht is the kelvin

temperature scale starting at absolute zero

how would you convert to kelvin → temperature and temperature → kelvin

Kelvin = degrees + 273

degrees = kelvin - 273

what is 100K in degrees

100 + 273 =373

what is 10 degrees in kelvin

10 - 273 =-263

what happens to the molecules when the temperature is increased

molecules would increase the average kinetic energy making them go faster

what is the relationship between the kelvin temperature and kinetic energy

they are directly proportional

if the temperature increases what happens to the pressure

the pressure increases because when the temperature increases it increases the average kinetic energy. This means more collisions, therefore more force is exerted.

if the volume increases what happens to the pressure

if the volume increases the pressure will decrease becuase molecules will have more room to move randomly, this means there are going to be less collisions therefore less force meaning less pressure.

what is the formula for Boyles law

p1 x v 1 = p2 x v 2

p1 = initial pressure

v1 = initial volume

p2= final pressure

v2 = final volume

for the Boyles to work, what has to be constant.

the temperature has to be constant

waht is the formula for gay lusacs law

p1/t1 = p2/t2

p1 = initial pressure

t1 = initial temperature

p2 = final temperature

t2 = final temperature

what needs to be constant for the gay lussacs law to work

the volume needs to be constant

what is the relationship gay lusaccs law

temperature and pressure is directly proportional

waht is the relationship in the Boyles law

volume and pressure is inversely proportional
