Acoustics: the study of sound waves
Sound is the phenomenon we experience when our ears are excited by vibrations in the gas that surrounds us.
As an object vibrates, it sets the surrounding air in motion, sending alternating waves of compression and

HEAT CONDUCTION EQUATION
Introduction
2-1C Heat transfer is a vector quantity since it has direction as well as magnitude. Therefore, we must
specify both direction and magnitude in order to describe heat transfer completely at a point. Temperat
