"Silent but Deadly" Gas Laws Exam "B"

Gas laws involve what three variables?

• Solid Liquid Gas 
• Speed Velocity Acceleration 
• Elements Compounds Mixtures 
• Pressure Temperature Volume 

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

What will happen to the volume of a gas if the pressure increases, with constant temperature ?

• Increase
• Decrease
• Nothing
• Explosion!

If you increase the pressure, what will happen to the temperature, if volume is constant?

• Increase
• Decrease
• Stay the same
• It will Blow Up

According to the Combined Gas Law, pressure and volume are inversely related which means that

• When pressure increases, volume increases
• When pressure decreases, volume decreases
• When pressure increases, volume decreases
• When pressure doubles, volume triples

You have a gas that has a pressure of 2 ATM and a volume of 10L.  What would be the new volume if the pressure was changed to 1 ATM?

• 5 L
• 20 L
• It would stay at 10L
• 1 L

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂

What is the equation for the combined gas law?

• P1 x V1 = P2 x V2

• V1/T1 = V2/T2

• P1 x V1 / T1 = P2 x V2 / T2

• P1 / T1 = P2 / T2

Which of the following conditions is STP?

• 0^o C

• 273 K

• 760 mm Hg

• 1 atm

• All of the above
