Overview

This course studies heat and the properties of matter, sound and light. It covers topics of temperature and thermometers, the zeroth law of thermodynamics and ideal gases, the amount of heat and thermal energy, elasticity, stress and strain, fluid mechanics, mechanical waves (transverse and longitudinal), electromagnetism and the resulting phenomena.

Intended learning outcomes

By studying this course the student will be able to:1- Know temperature and its units, the zeroth law of thermodynamics and thermal expansion.2- Compare different temperature units.3- It relates the coefficients of thermal expansion (longitudinal, surface and volume) and how to use them to calculate the effect of heat on objects.4- Explain some phenomena such as phase change according to the laws of heat transfer5- The amount of work done on a substance (gas or ....) is calculated as a result of the absorption or loss of its heat.6- Comparing the actual weight with the apparent weight of objects immersed in fluids and linking that to some natural phenomena.7- Explain the concept of wave and wave equation.8- Compare sound and light waves.9- Explain the reality of some optical phenomena as the phenomenon of (the light dimension).10- It connects the phenomenon of total reflection with what happens in optical fibers.
