* HEAT
** OBJECTIVES
1. Differentiate heat and temperatre
2. Infer the ncessary conditions for heat transfer to occr
3. appreciate heat transfer

*** THERMAL ENERGY
This referrs  to tthe energy  possessed by an  objecitve or
system due  to movement of  particles within the  object or
the system due to the movement of particles

When thermal energy is transformed, it is always produced.

**** HEAT
This  is  the  flow  of thermal  energy,  the  energy  that
transfers from  a body with  a higher temperatre to  a body
witth a lower temperatre.

SI Unit is Jules

There's also:

***** Calorie
   quantity of heat  needed to raise the  temperatre of one
   gram of water one

***** British Thermal unit

**** TEMPERATURE
This  measures the  average energy  of the  motions of  the
molecules in  the substance,  this can  be measred  using a
thermometer

There are three units used

|---------+------------+--------+---------|
| Celcius | Fahrenheit | Kelvin | Rankine |
|---------+------------+--------+---------|

The SI UNIT of this is Kelvin.

The Celcius is created by Anders Celsius of Sweden. The
Fahrenheit meanwhile is created by..


*** HEAT TRANSFER
The  process wherein  thermal energy  is exchanged  between
objects due to their temperatuure differences

Thermal Equillabrium  is the point where  the heat transfer
stops 

**** CONDUCTION
This  takes  place  between  objects thatt  are  in  direct
contact with each other, this is most effect in solids, the
reason why pans  are made of metal is  because they're good
conductors of heat

There  are also  insulators, materials  that transfer  heat
poorly, these things have rubber handles, etc. that prevent
us from getiing burned
**** CONVECTION
This  is   the  method  of  heat   transfered  through  the
circlation of liqid and gas

This is effective in fluids, this is the transfer of energy
bt  the  risking  or  sinking   of  matter  de  to  density
differences
**** RADIATION
The heat moves  throgh an empty space  (outer space), There
is no medim  like water, air, nor any  solid material where
heat can travel through

This   is   also  a   transfer   of   heat  by   means   of
electronmagnetic waves.
