TOPIC 3: STATES AND CHANGES OF STATES OF MATTER.

STATES AND CHANGES OF STATES OF MATTER.

LEARNING OUTCOMES The learner should be able to:

a. understand that matter is anything which occupies space and has mass and can exist in a solid, liquid, gas, and plasma form (u)

b. understand that solids, liquids, and gases have different properties including shape, pouring, and compressing (u, s)

c. know the kinetic theory ofmatter and use it to explain particle arrangement, inter-particle forces, movement of particles and the properties of solids, liquids, and gases (k, u)

d. understand that a change from one state to another involves either heat gain or heat loss (u, s)

e. appreciate the cooling effect of evaporation and how this contributes to maintaining constant body temperature (k, u, s)
