Question 9

Kinetic molecular Theory of gases

Answer 9

1. particles have negligible Volume.
2. There e are no intermolecular attractions or repulsions.
3. Molecules ar ein continuous and random motion.
4. Collisions are elastic. Conservation of Kinetic Energy is observed.
5. The average kinetic energy of gas particles is proportional to the absolute temperature.

Question 10

Daltons Law of partial pressures

Answer 10

In a mixture of gases, total pressure equals the sum of the pressures for each individual gas.
PA= XA Ptotal

Question 11

Boyle’s Law

Answer 11

at constant temperature, the volume of a gas is inversely proportional to its pressure
P1 V1= P2 V2

Question 12

Charles’s Law

Answer 12

at constant pressure, a gas volume is directly proportional to its temperature.
(V1/T1)= (V2/T2)

Question 13

Avogadros’ Law

Answer 13

The volume of a gas is directly proportional to the number of moles of the gas in.
(V1/n1)= (V2/n2)
