Expansion and Contraction of Solids and Liquids
This program covers the important topic of expansion and contraction of solids and liquids in Physics. We begin by discussing the nature of expansion and contraction and how this process occurs as a result of temperature change. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.
