What is the Ideal Gas Law equation?
PV = nRT
True or False: Avogadro’s Law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
True
What is the relationship described by Gay-Lussac’s Law?

Fill in the blank: The equation for Gay-Lussac’s Law is ______.
P1/T1 = P2/T2
What does the variable ‘R’ represent in the Ideal Gas Law?
R represents the ideal gas constant.
Which unit is commonly used for pressure in gas law calculations?
Atmospheres (atm)
True or False: The volume of a gas increases when the temperature decreases at constant pressure.
False
What is the effect of increasing temperature on the volume of a gas at constant pressure?
The volume increases.
Fill in the blank: According to Avogadro’s Law, 1 mole of any gas occupies ______ liters at standard temperature and pressure (STP).
22.4
What is the standard temperature in Kelvin?
273.15 K
What is the relationship between pressure and volume according to Boyle’s Law?
They are inversely proportional.
What does ‘n’ represent in the Ideal Gas Law?
‘n’ represents the number of moles of the gas.
True or False: The Ideal Gas Law applies perfectly to all gases under all conditions.
False
What happens to gas pressure if the volume is halved while temperature remains constant?
The pressure doubles.
What is the unit of the ideal gas constant R in the equation PV = nRT?
The unit of R is typically L·atm/(K·mol).

Gay-Lussac’s Law
What is the primary assumption of the ideal gas model?
Gas particles do not interact and have negligible volume.
Which gas law would you use to calculate the final volume of a gas when its temperature is increased at constant pressure?
Charles’s Law.
What does a graph of Charles’s Law look like?
A straight line with volume on the y-axis and temperature on the x-axis.
True or False: Increasing the amount of gas in a fixed volume increases the pressure.
True
