#### Transcript of Combine Gas Law

Boyles' Law when the temperature is constant, equal pressure is inversely proportional to the volume. Gay-Lusac's Law when volume is constant, the pressure
is proportional to temperature. Charles' Law Combined Gas Law Process (P V =P V) X (V/T=V/T)

(P V/T=P V/T) X (P/T=P/T)

P V/T=P V/T-simplify when pressure is constant the volume
is proportional to temperature. Combined Gas Law Baby Group 5 3-S
the ratio of the product of pressure and volume and the absolute
temperature of a gas is equal to a constant. V /T=V /T P V =P V 1 1 2 2 1 1 2 2 P /T=P /T 1 1 2 2 PV/T=PV/T

Temperature - 273.15 K K=C+273.15 mmHg/torr = unit of preassure Problem 2.00 L of a gas is collected at 298.0 K and 745.0 torr. What is the volume at STP Problem 2 If a bicycle tire has a volume of o.5m at 20C and 760 torr, figure out the volume when taken into the mountains where the preassure is 720 torr and the temperature is 14C.
