Write an essay explaining your drawing of how Heat is added, released and transferred from one object to another. Also, be sure to write your explanation for sublimation or depositiion as well.

here is a start

The most important concept to understand within the fire phenomena is heat transfer. Heat transfer is everywhere within the aspects of fire, such as fire development. Before the three types of heat transfer can be explained, a few more things need to be understood. Such as heat is the transfer of energy based on a temperature difference between two objects. Also that temperature is a measure of kinetic energy of the molecules in an object. Now the three types of heat transfer and first up is Conduction which is the transfer of energy in the form of heat by direct contact through excitement of molecules with driven by a temperature difference. Energy travels from a high to a low and the same thing happens with heat. When the high temperature molecules collide with the low temperature molecules, a transfer of energy occurs from the hot, more energetic molecules to the colder, less energetic molecules and this is recognized as conduction. Conduction is most prevalent in solids but it can also be found in liquids and gases. The rate at which heat is transmitted through a material by conduction depends on thermal conductivity which is a characteristic of a material and its mass. The easiest way to think of conduction is to hold a metal rod by one end and put the other over a fire. Eventually the hot energetic molecules from the fire will transfer to the cold, less energetic molecules of the metal rod and slowly creep up the rod to the cold end where it is being held and then move to the hand and cause burns. The second method of heat transfer is convection which is the transfer of energy through a circulating gas or liquid to or from a solid object. An example of convection is a pot on the hot

stove to the water inside which then heats up the pot and the that heats up the water. Convection consists of two energy transfer mechanisms. The first occurs
