everyone is always wondering what is heat? where does heat come from. well to answer all of your questions we well to talking about heat. Heat comes from heated things such as, heaters, the sun and the human body. There are three different types of heat: 1) conduction-energy is transformed but particles are not moved out of position. 2) convection-it moves in a circular pattern forming convection current. 3) Radiation-transfer of energy in the form of a wave.

So now you know where heat comes from and the three different types of heat. So now it is time to know what heat is, Heat: energy which is transferred form hotter substances to cooler substances.

Some more facts about heat is : temperature describes how hot or cold an object is. Scientists use the particle theory of matter to describe temperature. Knowing the temperature of common thing such as room and body temperatures, helps you better understand temperatures of less common things. Maintaining a constant body temperature is critical to you health. A person might now be able to recover if hypothermia is prolonged. Temperature scales are based on refer4ene points such as the freezing points to boiling points of water. To construct a thermometer, you need something that changes visibly as the temperature changes.
