Question 1

What does the atomic theory state?

Answer 1

• All matter is composed of atoms.
• Atoms cannot be created nor destroyed, they can be rearranged during chemical reactions.
• (Physical and Chemical properties of matter depend on the bonding and arrangement of these atoms).

Question 2

Pure substance vs Mixture

Answer 2

• PS has a fixed chemical composition
• mixture components retain their individual properties.

Question 3

Filtration

Answer 3

The method of separating one or more components from a mixture using filter paper that extracts components with a larger particle size.

Question 12

Whys kelvin used?

Answer 12

• Proportional to the average KE of particles.
• 0 in K implies that particles cannot transfer any kinetic energy on collisions.
• At 0 matter cannot lose heat.
