Gas Laws and Percent Composition

Flashcards covering Boyle's Law, Charles's Law, the Combined Gas Law, and calculation of percent composition.

According to Boyle's Law, what is the relationship between pressure and volume?

Inverse

According to Charles's Law, what is the relationship between volume and temperature?

Directly proportional.

What is the Combined Gas Law?

Combines Boyle's and Charles's laws: P₁V₁/T₁ = P₂V₂/T₂

Deposition

gas to solid

Sublimation

Solid to Gas

Condensation

Gas to liquid

Solid

Definite volume, definite shape, certain change

What do particles of a solid look like?

Close together, fixed in one spot and vibrating in place

liquid

Indefinite shape, definite volumes takes shape of container

What does a liquid particle look like?

Close together, constantly moving, swimming to each other

Gas

Indefinite shape and volume compresses able

What do Gas Particles look like?

far apart, constantly in rapid motion, flying around

Conduction

Heat transfer from contact on molecules (ex. Egg cooking in hot pan$

Convection

Heat transfer by fluids air or water (ex. Water in tea bag begins to boil)

Radiation

Emission of electromagnetic radiation (ex. Ice melting in the sun)

Thermal energy

Potential energy

Stored energy

Thermal equilibrium

Energy of an object due to the random motion of its particles

Energy

Ability to work

Kinetic Energy

Energy in motion
