Boyle's and Charles' Laws

At a constant pressure, the volume decreases in Charles' Law. What happens to the temperature?

• increases

• decreases

• stays the same

At a constant temperature, pressure increases in Boyle's Law. What happens to the volume?

• increases

• decreases

• stays the same

According to Boyle's Law, when the pressure of a gas increases at a constant temperature, its volume:

• decreases
• increases
• stays the same
• increases, then decreases

Boyle's law deals with:

• pressure and temperature
• temperature and volume
• pressure and volume
• starting and stopping

How do you convert Celsius to Kelvin?

• Add 273
• Subtract 273
• You can't convert those
• They are the same thing

A gas at STP would be under the following conditions:

• T = 25 C

  P = 1 atm

• T = 0 C

  P = 0 atm

• T = 0 C

  P = 1 atm

• T = 0 C

  P = 2 atm

What is 50 C in Kelvin?

• 223

• 323

• 100

• 50

What is the correct formula for Boyle's Law?

• V₁/T₁=V₂/T₂
• P₁/V₂=P₂/V₁

• P₁/T₁=P₂/T₂
• PV=nRT

What would you expect to see if temperature increased if you were using Charles's Law?

• volume would decrease proportionally

• volume would increase proportionally

• pressure would increase proportionally

• pressure would decrease proportionally

If temperature increases and the pressure is constant, the volume ___________

• Increases
• Decreases
• Stays the same
• Is variable
