 Plasmas  Bose-Einstein condensates Where do they exist?

 Enthalpy: How much energy is present Example: Pot on the stove  Burner off – low enthalpy  Burner on – high enthalpy

 Common forms of energy: Thermal (heat) Kinetic (movement) Potential (stored) Electromagnetic (electricity/magnetis m)

ENDOTHERMICEXOTHERMIC System Environment

ENDOTHERMICEXOTHERMIC  Heat moves from environment to system  Examples melting ice cubes (fusion) cooking an egg (boiling) converting frost to water vapor (melting, vaporization, and sublimations are endothermic processes) splitting a gas molecule mixing a cold pack dry ice (sublimation)  Heat moves from system to environment  Examples  Water vapor forming dew (condensing)  Formation of Ice (freezing)  Rusting iron  Burning of wood (combustion)  Snow forming in the clouds (deposition) HEAT moves towards the COLD
