Gas Laws

Which law states the following: The volume of a fixed mass of gas varies inversely with the pressure at constant temperature.

• Charles's Law
• Boyle's Law
• Gay-Lussac's Law
• Dalton's partial pressure law

What is the formula representation of Boyle's Law?

• P₁V₁ = P₂V₂
• V₁/T₁=V₂/T₂
• P₁/T₁=P₂/T₂
• P₁V₁/T₁ = P₂V₂/T₂

A balloon filled with helium gas has a volume of 500 mL at a pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km, where the pressure is 0.5 atm. If the temperature has remained constant, what volume does the gas occupy at this height?

• 250 mL
• 1000 mL
• 500 mL
• 200mL

What is absolute zero?

• when water freezes
• the lowest achievable temperature on the Kelvin scale
• equals zero degrees Celsius
  

Convert 50°C to kelvin

• 323.5 K
• 223.15 K
• 13657.5 K
• 5.463 K

______ states that volume of a fixed mass of gas at constant pressure varies directly with the temperature in kelvin.

• Combined gas law

What equation best represents Charles's Law

• P₁V₁ = P₂V₂
• V₁/T₁ = V₂/T₂
• P₁/T₁ = P₂/T₂
• P₁V₁/T₁ = P₂V₂/T₂
