Combined Gas Laws

if I initially have 4.0L of a gas and a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm?

• 1.3 L

• 13 L

• 130 L

• 400 L

A gas is heated to 150.0 degrees C until it occupies a volume of 12.8 L. If the original temperature was 85.0 degrees C, what was the original volume?

• 10.83 atm

• 1083 L

• 11 L

• 10.83 L

a rigid Nalgene bottle filled with gas is placed in ice. What will happen to the pressure of the gas? Be sure to include the motion of the particles in your explanation

• the pressure will decrease because temperature and pressure are directly related. The gas particles will not occupy as much space, as they get closer together when the temperature decreases.

• the pressure will increase

• the pressure will stay constant

• the temperature will decrease

an infected tooth forms an abscess that fills with gas. The abscess puts pressure on the nerve of the tooth, causing a toothache. While waiting to see a dentist, the person with the toothache tried to relieve the pain by treating the infected area with moist heat. Will this treatment help?

• the treatment will help because the increasing temperature will decrease pressure.

• the treatment will not help because by increasing the temperature, the particles move away from each other faster, causing more collisions and more pressure. You should ice a toothache

what will happen to pressure if the temperature stays constant and volume increases?

• pressure will decrease

• pressure will increase

• pressure will stay constant

when the pressure goes up, the temperature goes ___

• the temperature goes up

• the temp goes down

• the temp stays constant

in a balloon, there is 1.1 atm of pressure, held at a volume of 10L. When the balloon deflates, there is .5 atm of pressure. What is the volume after the balloon deflates?

• 10.5L

• 22mL

A 7 liter container of hydrogen has a pressure of 50 atm. What would the volume be if you decrease the pressure to 15 atm?
