Gas Laws Review

As the temperature of a given sample of a gas decreases at constant pressure, the volume of the gas

• increases

• decreases

• remains the same

The kinetic molecular theory assumes that the particles of an ideal gas

• are in random, constant, straight-line motion

• are arranged in a regular geometric pattern

• have strong attractive forces between them

• have collisions that result in the system losing energy

Which temperature unit must be used when doing gas law calculations?

• degrees Fahrenheit

• degrees Celsius

• Kelvin

• degrees Rankine

Which temperature is the same as 13 degrees C?

• 260 K

• 286 K

• 747 K

• 773 K

According to the kinetic molecular theory, which statement describes the particles of an ideal gas?

• the gas particles are arranged in a regular pattern

• the force of attraction between the gas particles is strong

• the collisions of the gas particles may result in the transfer of energy

 The temperature of a substance changes from 173 degrees Celsius to 0 degrees Celsius. What is this temperature change when reported in Kelvin?

• 100

• 173

• 273

• 446

Points A, B, and C, represent the ____, ____, and ____ phases, respectively

• gas, liquid, solid

• gas, solid, liquid

• solid, gas, liquid

• solid, liquid, gas
