11.3 volume and temperature of an ideal gas

27/5/25

amount of gas measured in

n/m

increase in temperature

increase in collision frequency and collision energy, increase in volume

decrease temperature

decrease collision frequency and collision energy, decreased volume

temperature and volume have a

direct relationship at constant n/m and P

convert °C to K

add 273.15

convert K to °C

subtract 273.15

charles law

volume is directly proportional to the temperature of an ideal gas as long as the temperature is in Kelvin and constant number of moles per mass

charles law derived equation

V₁ / V₂ = T₁ / T₂ (T must be in Kelvin)

gay-lussacs law

pressure is directly proportional to temperature (in Kelvin) as constant # of moles per mass and volume

gay-lussacs law derived equation

P₁ / P₂ = T₁ / T₂ (T must be in Kelvin)

standard conditions

• P_STP = 101.3 kPa

• T_STP = 0.00000 degrees C or 273.15 K

standard ambient T and P

• P_SATP = 100.0 kPa

• T_SATP = 25.00 degrees C = 298.15 kPa
