Kinetic Theory Pre-Class Quiz

What is the main idea of the Kinetic Theory of Gases?

• Gases are made of particles that are always at rest.

• Gas particles move in random directions and collide with each other.

• Gas particles are tightly packed and vibrate in place.

• Gas particles are constantly attracted to each other.

Which of the following statements is true about the particles in a solid?

• They move freely and are far apart.

• They are tightly packed and vibrate in place.

• They move in straight lines with high speed.

• They have no fixed position and flow like a liquid.

What happens to the volume of a gas when its pressure is decreased, assuming temperature is constant?

• The volume increases.

• The volume decreases.

• The volume stays the same.

• The volume becomes unpredictable.

According to Boyle's Law, if the pressure of a gas is doubled, what happens to its volume?

• The volume is halved.

• The volume doubles.

• The volume remains the same.

• The volume increases exponentially.

Which gas law explains the relationship between the volume and temperature of a gas at constant pressure?

• Boyle's Law

• Charles' Law

• Dalton's Law

• Ideal Gas Law

What does the Combined Gas Law describe?

• The relationship between the volume, pressure, and temperature of a gas, assuming the number of particles is constant.

• The behavior of gases at very low temperatures.

• The relationship between volume and pressure of an ideal gas.

• The behavior of gases in a closed container.

What happens to the pressure of a gas when its temperature increases, assuming the volume is constant?

• The pressure decreases.

• The pressure remains unchanged.

• The pressure increases.

• The pressure becomes zero.

What is the Ideal Gas Law equation?

• PV = nRT

• V = P/T

• P = kV

• V = mRT

According to Dalton's Law of Partial Pressures, the total pressure of a gas mixture is the sum of the pressures of the individual gases. Which of the following is correct?

• The partial pressure of each gas depends on the temperature.

• The partial pressures of gases are independent of each other.

• The partial pressures of gases are always equal.

• The total pressure depends only on the volume.

Which of the following occurs during the process of melting?

• Particles move closer together as a solid becomes a liquid.

• Particles gain enough energy to move freely as a liquid becomes a gas.

• Particles gain energy and begin to move more rapidly as a solid becomes a liquid.

• Particles lose energy and slow down as a liquid becomes a solid.
