States of matter - The gaseous state

Question 1

What is the basic assumptions of kinetic theory as applied to the ideal gas?

Answer 1

• Gas particles have negligible size or volume
• The intermolecular forces between gaseous particles is negligible
• The gas particles are in constant random motion
• Collisions between gas particles are perfectly elastic
• The KE of particles is directly proportional to the temperature

Question 2

Real gases

Answer 2

• The molecules have certain volume

- the intermolecular forces between real gases is not negligible

Question 3

How to make the real gases acts like an ideal gas?

Answer 3

Low pressure
-Gas molecules widely spread
-The intermolecular forces between molecules is negligible
High Temperature
-High KE, hence able to overcome the intermolecular forces of attractions
-do not stick together when they collide

Question 4

How to make real gas deviates more than ideal gas?

Answer 4

• High pressure

- Low temperature

Question 5

What is the general gas equation?

Answer 5

pV = nRT
