DIAGNOSTIC TEST (SCIENCE 10)

Which of the following is NOT assumed by the Kinetic Molecular Theory (KMT)?

• Gas molecules exert attractive and repulsive forces on each other

• Gas molecules are considered as point particles with no volume

• Gas molecules are temporarily colliding with each other and with the walls of container

• Gas molecules are constantly in motion, they move in a straight line and the motion is at random

What gas law states that volume is directly proportional to temperature?

• Avogadro's Law

• Boyle's Law

• Charles' Law

• Ideal Gas Law

What gas law states that volume is inversely proportional to pressure?

• Avogadro's Law

• Boyle's Law

• Charles' Law

• Ideal Gas Law

What gas law states that volume is directly proportional to number of moles?

• Avogadro's Law

• Boyle's Law

• Charles' Law

• Ideal Gas Law

A student inflates a balloon with helium then places it in the freezer. The student should expect ______________.

• the balloon's volume to increase

• the balloon's moles to increase

• the balloon's volume to decrease

• the balloon's moles to decrease

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?

• The pressure will increase

• The pressure will remain constant

• The pressure will decrease

• The pressure will equalize

Charles' Law States _________________.

• As pressure goes up volume goes down

• As volume goes up temperature goes up 

• As pressure goes up temperature goes up

• As pressure goes down volume goes down 

Pressure is __________.

• defined as the mass that an object exerts when at rest.

• defined as the number of moles of substance divided by the mass of the substance.

• not a measurable in gases.

• created by the force of the gas particles impacting the walls of the container.

If the temperature of a gas increase, the pressure __________.

• decreases

• increases

• does not change

If a balloon is cooled what will happen to the volume?

• Volume will increase

• Volume will decrease

• Volume will not change

• all of these
