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/magnetism)
ENDOTHERMIC EXOTHERMIC

EnvironmentEnvironment
ENDOTHERMIC EXOTHERMIC
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
