Another example is radiant energy - the energy we get from the sun. Heat is energy in the process of being transferred from one object to another because of the temperature difference between them. Before we do this lets discuss the concept of sensible heat, specific heat and latent heat. 1C. Water has a much higher capacity for storing energy than other substances -e.g. sand or air. The greater the temperature difference the faster the transfer.
Some materials are better conductors of heat than others, metals are good conductors, air is poor.
These waves have electric and magnetic properties - electromagnetic waves. Wave characteristics - horizontal distance between two successive crests is the wavelength. We will discuss this method more later in the course. Evaporation cools the environment. As molecules leave, faster ones leave first, average speed decreases and so the temperature of the object cools.
