States of Matter and Laws

Question 1

Boyle’s Law (def)

Answer 1

Volume of gas varies inversely with the pressure exerted by the gas if the temperature and number of moles are held constant. PV=Kb

Question 2

Boyle’s Law (formula)

Answer 2

PiVi = PfVf

Question 3

Charle’s Law (def)

Answer 3

Volume of a gas varies directly with the absolute temperature (K) if pressure and number of moles are constant V/T=Kc

Question 4

Charles’ Law (Formula)

Answer 4

Vi/Ti = Vf/Tf

Question 5

Gay-Lussac’s Law (def)

Answer 5

For a fixed amount of gas at constant volume, the pressure of a gas is proportional to its Kelvin temperature. P/T=Kg

Question 6

Gay-Lussac’s (formula

Answer 6

Pi/Ti = Pf/Tf

Question 7

Combined Gas Law Formula

Answer 7

PiVi/Ti = PfVf/Tf

Question 8

Combined Gas Law (formula)

Answer 8

PV = nRT

Question 9

Dalton’s Law of Partial Pressure (def)

Answer 9

A mixture of gases exerts a pressure that is the sun of the pressures that each has would exert if it were present alone under the same conditions

Question 10

Dalton’s Law of Partial Pressure (formula)

Answer 10

Pt = p1+ p2 + p3…. For ex. P air = P N2 + P O2

Question 11

Henry’s Law (def)

Answer 11

The number of moles of a gas dissolved in a liquid at a given temperature is proportional to the partial pressure of the gas above the liquid

Question 12

Raoult’s Law (def)

Answer 12

When a nonvolatile solute is added to a solvent, vapor pressure of the solvent decreases in proportion to the concentration of the solute.

Question 13

LeChatelier’s Principle

Answer 13

If a stress is placed on a system at equilibrium, the system will respond by altering the equilibrium composition in such a way as to minimize the stress.
