Calculate the volume that a 0.323-mol sample of a gas will occupy at -8oC and a pressure of 0.900 atm.
Gas particles are in constant motion. They travel in straight lines, and they constantly bounce off the walls of any container that holds them.
What does this constant bombardment of particles against the walls of the container create?
Pressure
Density
Temperature
Magnetism

A Scientist has a container with 8.20 liters of nitrogen gas at 200. K and a pressure of 121.56 kPa. How many moles of gas are in the container?
60.7 mol
0.599 mol
0.0799 mol
164 mol
Which of the following describes why the pressure of a gas in a rigid tank increases when temperature increases?
As temp increases, the particles have more space to move and decrease collisions with the tank.
As temp increases, the particles have less space to move and increase collisions with the tank
As temp increases, the particles slow down and decrease collisions with the tank.
As the temp increases, the particles speed up and increase collisions with the tank.
