G' Behavior of Gases

1
G. Behavior of Gases 1. Gas pressure is caused
by collisions of gas particles on surfaces.
2. Pressure is measured in pascals. 3. 1 Pa 1
N / m2 4. Standard air pressure at sea level is
101.3 kPa this is the same pressure as a big
truck (14.7 pounds / sq. inch). 5. We normally
use atm for problems

6. Boyles Law a. The volume of a gas
varies inversely with its pressure if temperature
remains constant. b. P1 V1 P2 V2
Pushing the plunger down will increase the
pressure
Volume of the gas inside the cylinder will
decrease

7. Charless Law a. The volume of a gas
varies directly with its temperature if pressure
remains constant. b. V1 / T1 V2 / T2
A balloon shrinks when submerged in cold water

8. Gay-Lussacs Law Pressure varies directly
with temperature if volume remains constant.
