Physics Concept: Melting
This picture of an ice cube demonstrates the physics concept of melting. Melting is the change in state of a substance from a solid to a liquid. In order for a solid to melt, there needs to be some sort of consumption of energy in the form of heat. Two different ways that heat goes into the water molecules include heat in matter and radiation. Heat can be present in a random manner that can include red hot metal, hot water or hot air. The transfer of heat is to other bodies and objects happen by contact. For this kind of heat transfer the contact area is decisive as in the amount of heat transferred in a certain time is directly proportional to the contact area. An example of radiation, the second way heat goes into water molecules, is sun radiation. Sun radiation warms up the air and therefore passes the heat through contact with the air. These are the two ways that heat is transferred in order for an ice cube to melt.
Two were taken and printed because I was unable to choose which one looked best.
