Pressure vs. Volume
Draw a particle diagram to represent the effect on pressure when the volume is changed, but the number of particles and temperature remain constant.

This will happen to pressure when temperature increases and volume decreases.
What is increase?
If I initially have a gas at a pressure of 12atm, a volume of 23L and a temperature of 200K and then raise the volume to 29L and increase the temperature to 300K, what is the new pressure of the gas?
What is 14atm?
This law relates the change in volume and the change in pressure.
What is Boyle's Law?
This law relates the number of particles and pressure.
What is Avogadro's Law?
Adding this number converts Celsius (°C) to Kelvins (K).
What is 273.15?
Standard temperature and pressure (STP) have these values.
What is 1 atm and 273 K.
I have an unknown volume of gas at a pressure of 0.5 atm and a temperature of 325K. If I raise the pressure to 1.2 atm, decrease the temperature to 320K, and measure the final volume to be 48 L, what was the initial volume of the gas?
What is ~117 L?
Pressure and volume have this relationship.
What is inversely proportional?
Pressure and Number of Particles have this relationship.
What is directly proportional?
Draw 2 graphs, one showing the relationship between temperature and pressure when temperature is measured in kelvins, and the other in celsius.
See drawings
Name the gas laws that makeup the combined gas law. (Mention all 3)
What are Gay Lussac, Boyle and Avagadro's Laws?
If I have 2.9 L of gas a pressure of 5 atm and a temperature of 50°C, what will be the temperature of the gas if I decrease the volume of the gas to 2.4L and decrease the pressure to 3 atm?
What is 160.38K?
When volume is quartered, pressure is.
What is quadrupled?
When the number of particles is tripled this happens to the pressure.
What is tripled?
A weather balloon is inflated to a pressure of 123.2kPa at a temperature of 295K. It is released and flys to the lower stratosphere at a temperature of 188K. What is the pressure?
78.5kPa
What is the formula for the Combined Gas Law?
((P1V1)/(T1/n1))=((P2V2)/(T2/n2))
Is I have 17L of gas at a temperature of 67°C and a pressure of 88.89 atm, what will be the pressure of the gas if I raise the temperature to 94°C and decrease the volume to 12L?
What is 136 atm?
Find the pressure if a 15L balloon with a pressure of 75kPa is compressed to 10L. (Show your work on a whiteboard, units required).
What is 112.5kPa.
In a syringe there are 15 particles at a pressure of 95kPa. If the pressure decreases to 73kPa, how many particles are in the syringe?
11 particles
You leave an empty 1L water bottle in your car at 10 am, when it is 37°C and 0.89atm inside your car. You come back to your car at 1pm and it is 49°C, what is the pressure now?
0.92atm
This is the resulting formula for the combined gas law if the temperature and number of particles remain constant.
What is P1V1=P2V2?
When a container of nitrogen has a volume of 15L and 103kPa, and contains 25 particles, this number of particles left the system when the nitrogen was moved to a 10L container at a pressure of 88kPa
What is 9 particles left the system?
