What is the base unit for volume?
Liters
What are the variables in this law?
Pressure and volume
What are the variables in this law?
Temperature and Volume
What are the quantities involved in this law?
Pressure and temperature
The formula for the combined gas law is..
P1V1/T1 =P2V2/T2
It is the base unit for Temperature.
Kelvin
What happens to pressure when particles collide frequently?
Increases
What happens to volume of the gas as the particle's kinetic energy increases?
Increases
To observe the relationship between temperature and pressure the container must be?
Rigid
Name the gas law that relates pressure, volume, and temperature of a gas when the amount of gas is constant.
Combined gas law
The temperature at which particles will theoretically stop moving.
Zero Kelvin or absolute zero
What did Boyle use to observe the relationship between pressure and volume?
Mercury and J-tube
How did Charles able to observe this law?
He used hot air balloons.
The relationship between pressure and temperature is..
Direct proportional
Why do you think degrees Celsius is not used in solving gas law problems?
We don't use Celsius in gas laws because it can give incorrect answers. Gas law equations require an absolute temperature scale like Kelvin to ensure accurate and proportional relationships between volume, pressure, and temperature.
If the problem requires atmospheric pressure as the unit, then 800 mm Hg is equivalent to…
1.05 atm
If a sample gas has a volume of 725 ml at standard pressure, what will the final pressure be if the volume decreases by 50% of its original volume?
2 atm
A sample of Helium gas has a volume of 250 ml in a flexible container. If the temperature increases from -15 oC to 100 oC, what is the new volume of the gas?
0.361 L
A pressure cooker was heated to 500 °C, which raised the pressure to 3.5 atm. If the initial pressure in the pot was at STP, what was the initial temperature?
-52 °C or 220.86 K
A gas occupies 2.5 L at a pressure of 1.0 atm and a temperature of 300 K.
What will be the new volume of the gas if the pressure increases to 2.0 atm and the temperature rises to 350 K?
1.46 L
