Unit 6 Review

A flexible container of gas is held at constant pressure. The gas is 4.8 L at a temperature of 200K. What would the new volume of a gas be if the temperature increased to 300K?

• 7.2 L

• 3.2 L

• 12,500 L

To convert a celsius measurement to kelvin, you add 273.

• True

• False

True or false:

Gas laws examine the relationship between pressure, volume, temperature, and moles of ideal gases.

• True

• False

Select all that is true of the kinetic molecular theory

• All matter is made of particles

• Temperature is a measure of how hot or cold matter is

• The particles are constantly in motion

• Explains the properties of solids, liquids, and gases

• All particles of matter have mass

A container of gas is held at a constant pressure. The volume of the gas increases in response to a change in temperature. Choose responses for 1. What the temperature change should be and 2. The correct reasoning.

• The temperature decreased.

• The temperature increased.

• Volume and temperature are directly related

• Volume and temperature are indirectly related.
