Gas Laws Quiz

If LESS collisions occur between gas molecules and the sides of a closed container, what effect will there be on the gas pressure?

• Gas pressure will increase

• Gas pressure will remain constant

• Gas pressure will decrease

• Gas pressure will approach absolute Kelvin

Pressure is defined to be

• The number of collisions of gas particles per mole of gas

• The average kinetic energy of the gas molecules

• The average potential energy of the gas molecules

• A force per unit area

Which diagram shows the highest pressure?

• I

• II

• I and II

• III

• volume

• pressure

• temperature

• amount of gas
