gas laws & the kinetic model Flashcards
pressure is defined as
the force per unit area
calculating pressure equation:
P = F divided by A
pressure is measured in
newtons per square metre ( Nm -2) / Pascals (Pa)
the pressure of a gas is caused by
the particles colliding with the container walls
in a gas at a low temp, the particles move
slowly
in a gas at a high temp, the particles move
quickly
the volume of a gas is
the space it occupies
if gas is at a constant temp,
P x V = constant
P1 x V1 = P2 x V2
absolute zero =
-273 degrees Celsius
if gas is at a constant vol,
P divided by T(in Kelvin) = constant
P1 divided by T1 = P2 divided by T2
to convert from celsius to kelvin,
add 273
to convert from kelvin to celsius,
minus 273
increase in temp of 1K is equal to
increase of 1 degrees celsius
V divided by T =
constant
