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

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
