Chemistry -- Gases

Who said that equal volumes of different gases under the same conditions have the same number of particles?

• Boyle
• Charles
• Graham
• Avogadro

How do you convert Celsius to Kelvin?

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

• V

The spontaneous spreading of a gas is called

• diffusion
• volume
• condensation
• convection

Whose law states that gases diffuse at a rate that is inversely proportional to the square roots of their molar masses?

• Boyle
• Charles
• Graham
• Dalton

Which gas would diffuse the fastest, helium, oxygen, or krypton?

• helium
• oxygen
• krypton
