Chemistry: Gas Laws

What creates pressure?

• gas molecules spinning

• gas molecules colliding with container walls

• potential energy

• electrons

What is the mathematical expression for Boyle's Law?

When using Charles' Law if you double volume, what happens to temperature?

• it remains constant

• it triples

• it is divided by 2

• it is doubled also

What temperature scale must we use in the Gas Laws?

• Rankine

• Fahrenheit

• Kelvin

• Celsius

How many kpa are in 1.01 bar?

• 760

• 101.3

• 14.7

• 1

How do we measure an increase in kinetic energy?

• volume

• temperature

• Liters

• none of the above

What happens to pressure as we in crease kinetic energy?

• it decreases

• it remains constant

• it increases

• none of the above

If you place a balloon in a refrigerator what will happen to the volume?

• it will decrease

• it will increase

• it will remain constant

• none of the above

Why does the volume decrease in the previous question?

• because the molecules slow down their spinning

• because temperature and pressure decrease with a decrease in kinetic energy and collisions

• because of a decrease in potential energy

• none of the above
