What is the equation for the Combined Gas Law?
Think of how Boyle's and Charles's Laws are combined.
Define pressure in the context of gases.
Consider what happens when gas molecules hit the walls of their container.
What does the Combined Gas Law allow us to calculate?
Think about the relationship among the three variables.
True or False: The temperature must always be measured in Celsius when using the Combined Gas Law.
Recall the conversion from Celsius to Kelvin.
A gas in a cylinder has an initial volume of 3.0 L at a temperature of 400 K and a pressure of 1.0 atm. How do its volume and pressure change if its temperature is increased to 500 K while keeping the volume constant?
Keep in mind the relationship P/T; P1/T1 = P2/T2.
You’re given a scenario: a helium balloon is at sea level with a volume of 2.0 L, temperature of 298 K, and pressure of 1 atm. If it rises to a height where the temperature is 250 K and the pressure is 0.5 atm, what will be the new volume of the helium in the balloon?
Remember to convert your temperature to Kelvin before using the formula.
