Gay-Lussac's Law

Gases exert a force per unit area on the walls of a container. This measurement is called _____________.

• pressure

• volume

• temperature

• kinetic energy

All gases are _________________.

• smelly

• colorful

• compressible

• cohesive

The pressure of a gas ____________ with increased temperature.

• decreases directly

• increases directly

• stays the same

• varies inversely

Which statement most accutaely depicts Gay-Lussac's Law?

• Describes the direct relationship between PRESSURE and TEMPERATURE of a gas at constant volume.

• Describes the inverse relationship between PRESSURE and TEMPERATURE of a gas at constant volume.

• Describes the direct relationship between VOLUME and TEMPERATURE of a gas at constant pressure.

• Describes the direct relationship between PRESSURE and VOLUME of a gas at constant temperature.

7. Determine the pressure change when a constant volume of gas at 2005 kPa is heated from 40 °C to 60 °C. What is T2 in the calculation for this problem?

• 40 °C

• 60 °C

• 313 K

• 333 K

Pick the correct setup for this problem:

If a gas is cooled from 350 K to 280 K and the volume is kept constant what final pressure would result if the original pressure was 720 mm Hg?

• 280 x 350= 720 x P2

• P2= 720 x 280 x 350

• 720 x 280= P2 x 350

• 720 x 350= P2 x 280
