A balloon has a volume of 9 L at 3 atm. What would be the volume if the pressure changes to 6 atm without changing the temperature?
(a)
A gas is compressed from 8 L to 4 L at constant temperature. If the initial pressure was 1 atm, what is the final pressure?
(a)
A gas in a cylinder occupies 12 L at 273 K. What will be the volume at 546 K, assuming pressure remains constant?
(a)
At 250 K, a gas occupies a volume of 8 L. What will be the volume at 500 K if pressure remains constant?
(a)
A gas is at 800 kPa and 350 K. When heated to 700 K at constant volume, what will the pressure become?
(a)
The pressure of a gas is 300 mm Hg at 400 K. If the temperature is lowered to 200 K at constant volume, what is the new pressure?
(a)
A gas at 3 atm and 10 L is heated from 300 K to 600 K. If the pressure changes to 6 atm, what is the new volume?
(a)
A gas occupies 8 L at 1 atm and 273 K. If the volume changes to 6 L and the pressure changes to 2 atm, what is the new temperature?
(a)
The ideal gas law formula is:
(a)
If the number of gas particles in a container is doubled while volume and temperature remain constant, what will happen to the pressure?
Pressure will remain the same
Pressure will halve
Pressure will double
Pressure will quadruple
What does the constant R represent in the ideal gas law equation PV = nRT?
Relative Pressure
Standard Pressure
Ideal Gas Constant
Rate of Reaction
When you increase the temperature of a gas while keeping volume constant, what happens to the gas molecules?
They slow down
They move faster and increase pressure
They move faster in random directions
They remain constant
What is the term for the temperature at which all substances stops moving?
Critical Temperature
Freezing Point
Absolute Zero
Absence of Heat
According to the kinetic molecular theory, gas particles:
Have significant volumes and strong attractions
Are all the same size and mass
Are stationary and exerts no pressure
Move randomly with elastic collisions
The pressure exerted by each gas in a mixture is called:
Absolute Temperature
Partial Pressure
Total Pressure
Atmospheric Pressure
