Scientific Laws

Question 1

states that equal volumes of all ideal gases (at the same temperature and pressure) contain the same number of molecules.

Answer 1

Avogadro’s Law

Question 2

states that equal pressure is inversely proportional to volume (when temperature is constant).

Answer 2

Boyle’s Law

Question 3

states that volume is proportional to temperature (when pressure is constant). Remember that temperature must be measured in Kelvin.

Answer 3

Charles’s Law

Question 4

states that pressure is proportional to temperature (when volume is constant).

Answer 4

Gay-Lussac’s Law

Question 5

Combining Charles’s Law, Boyle’s Law, and Gay-Lussac’s Law

Answer 5

Combined Gas Law

Question 6

A chemical compound, no matter what its origin or its method of preparation, always has
the same composition; i.e., the same proportions by mass of constituent elements.

Answer 6

Law of Definite Proportions

Question 7

If two elements form more than a single compound, the masses of one element combined
with a fixed mass of the second are in the ratio of small whole numbers.

Answer 7

Law of Multiple Proportions
