APBI 244

Radiant energy

Electromagnetic waves (Sun, hot fire, clouds)

Sensible heat

Due to changes in temperature without phase changes, thermal energy we can feel (warm air)

Latent

Due to phase changes of a substance without temperature changes, especially (cooling we feel after getting out of the swimming pool)

Chemical energy

Fixed in conversion of CO2 to carbohydrate (CH2O) (photosynthesis)

Kinetic

Due to motion (winds)

Geopotential

Due to position in gravitational fiedl (geopotential height)

Radiation’s energy transfer is through.. example of radiation

Electromagnetic waves, checking if the burner is on by putting your hand over to feel the warmth

Conduction’s energy transfer is through.. example of conduction

Molecular motion,metal spoon getting hot when dropped in pot of boiling water

Convection’s energy transfer is through.. example of energy flux density

Mass movement in a fluid , warm water rises and cool water sinks in the pot

Energy

The ability to do work (In J - Joules)

Energy flux

The rate of work or the flow rate of energy in (W - Watts = J s^(-1))

Energy flux density

The flow rate of energy per unit (surface) area (Wm^-2 = J s ^(-1) m^(-2))

Mass flux dnesity

Is the flow rate of mass per unit (surface) area
