Gas Laws And The Mole

Question 0

Boyle’s Law

Answer 0

At a constant temperature the volume of a given mass of any gas in inversely proportional to the pressure of the gas

Question 1

Diffusion

Answer 1

Is the spontaneous spreading out of a substance due to the natural movement of its particles

Question 2

Charles’s Law

Answer 2

At a constant pressure, the volume of a given mass of any gas is directly proportional to the Kelvin temperature

Question 3

Gay-Lussac’s law of combining volumes

Answer 3

When gases react the volumes consumed in the reaction bear a simple whole number ratio to each other and to the volumes of any gaseous product of the reaction if all volumes are measured under the same conditions of temp and pressure

Question 4

Avogadro’s Law

Answer 4

Equal volumes of gases under the same conditions of temperature and pressure contain equal numbers of molecules

Question 5

An ideal gas

Answer 5

Perfectly obeys all the gas laws under all conditions of temperature and pressure

Question 6

A mole of a substance

Answer 6

I’m

Question 7

The relative molecular mass

Answer 7

The average mass of a molecule of the substance relative to 1/12 of an atom of C12
