States of Matter:- Solids (dense, fixed shape)- Liquids (dense)- Gases (not dense) This week: Temperature and Heat James scholars honors credit Temperature Context: Boiling water is hot. Ice is cold. When it snows, the air is cold. Objective: Describe how hot or cold a material (solid/liquid/gas) is.- Temperature is a measure for heat content = thermal energy = the energy that can be removed from/added to matter by bringing it in contact with other matter. Transferred thermal energy is called heat .- There is a minimum temperature , where all particles are at rest (0K).- When two materials are in contact, heat flows from the hot to the cold object , and eventually the two materials have the same temperature...
