GAS LAWS
What's the relationship between pressure and volume?
As the pressure of a gas increases, volume decreases accordingly. P1/V1 = P2/V2
Temperature
The temperature inside a fridge is about 5°C. If a balloon is placed in the fridge that has an initial temperature of 25°C and a volume of .7L, what will the volume of the balloon be when it is fully cooled?
.65L
If you're solving for pressure, what R value do you use?
Convert -85°C to K
188K
What's the relationship between volume and temperature?
Volume increases as temperature increases.
V1/T1 = V2/T2
Size of the container
Volume
A gas occupies 15.3 L at a pressure of 55mmHg. What is the volume when the pressure is increased to 75 mmHg?
11.22L
What 3 Factors are directly related to the Pressure of a system
The number of moles, the volume, and the temperature
Convert 6 atm to mmHg
4560 mmHg
As temperature increases, pressure increases.
P1/T1 = P2/T2
Number in force of molecule collisions
Pressure
A gas occupies a volume of 4 liters at 25C and a pressure of 2 atm. If the temp is decreased to 0C and the pressure increased to 4 atm, what will the new volume of the gas be.
Volume = 1.83 liters
A gas at a pressure of 1 atm, volume of 10 liters, and temperature of 25ºC is compressed to liters and heated to 50ºC. What will be the final pressure
2.17 atm
Convert 140mmHg to kPa
18.66 kPa
What is the equation for the ideal gas law?
PV=nRT
273K, 0º C 1atm, 760mmHg, 101.3kPa
The volume of a gas-filled balloon is 50L at 35°C and 153 kPa. What volume will the balloon be at STP?
66.94L
What pressure is exerted by .00573mol of gas in a 27.8mL container at 11º C?
4.8 atm
Convert 215 kPa to atm
2.12 atm
What is the equation for combined gas law?
P1xV1/T1=P2xV2/T2
Theoretical temperature
What volume is occupied by .754 mol of gas at 95.6 kPa and 8°C
18.43L
Why does a notecard stay attached to the cup of water even when flipped over?
The atmospheric pressure pushes on the pressure in the cup. The lack of air molecules in the cup creates an area of low pressure and low collisions.
The atmospheric pressure in a mountainous location is measured to be 613 mm Hg. what is this pressure in atm and in kPa
atm: .807 kPa: 81.7
