Diagram showing a metal being heated
WebEnergy flow diagrams Diagrams can be used to show how energy is transferred from one store to another. Two examples are the transfer diagram and the Sankey diagram. WebMaterials with a high thermal conductivity constant k k k k (like metals and stones) will conduct heat well both ways; into or out of the material. So if your skin comes into contact with metal that is colder than your skin temperature, the metal can rapidly transfer heat energy out of your hand, making the metal feel particularly cold.

WebThe particle model has four main tenets: All substances are made of particles. The particles are attracted to each other (some strongly, others weakly). The particles move around (have kinetic energy). As temperature increases, the particles move more (their kinetic energy increases). A solid particle diagram. WebQ10.
