11.2 pressure and volume of ideal gasses relationship

26/5/25

P is ______ related to..

inversely related to V

P = k (1/v) or

PV = K

pressure is ________ proportional to

inversely proportional to volume of an ideal gas

P₁ V₁ = k, P₂ V₂ = k

P₁ V₁ = P₂ V₂

standard atmospheric pressure: kPa

101.3 kPa

standard atmospheric pressure: atm

1.00 atm

standard atmospheric pressure: mmHg or torr

760.0 mmHg or 760.0 torr

what 3 values are all directly proportional?

101.3 kPa = 1.00 atm = 760.00 mmHg or 760.0 torr

convert 96.8 kPa to mmHg

96.8 kPa/101.3 kPa = x mmHg/760.0 mmHg
x mmHg = 96.8 kPa x 760.0 mmHg /101.3 kPa

= 726.2 mmHg
