Gas Law Part 2

Which of the following equations represents the Ideal Gas Law?

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• PV = nRT

• P₁/T₁ = P₂/T₂

In the Ideal Gas Law (PV = nRT), which variable represents the number of moles of gas?

• P

• V

• n

• T

According to Avogadro's Law, equal volumes of gases at the same temperature and pressure contain:

• Different numbers of molecules

• Equal numbers of molecules

• Different masses of molecules

• No molecules

Which of the following is a correct value for the Ideal Gas Constant (R) when using units of L·atm/mol·K?

If you increase the number of moles of a gas in a container while keeping the temperature and pressure constant, what will happen to the volume?
