J is the unit of heat. it is the short form of Joule.【物】焦耳(功或能的單位)
the larger units of energy are Kilojoule(kJ) and megajoule.(MJ)

W is the unit of Power.It is the short form of Watt.【電】瓦(特)
1W=1Js-1

'C shoul be Degrees Celsius. (On the Celsius temperature scale,the range between the lower and upper fixed points is divided into 100 equal divisions called Degrees Celsius)

E is the short form of energy, Named by James Joule.Energy is devided into Internal energy .It is the sum of Kinetic and potential energy of all its particles.


energy tramsferired should be written as Energy transferred . It is the heat transferred from a hot body to a cold body,untill the temperature is the same This process we called Energy Transferred.

J = joule = the unit of energy
W = wok = the unit of power
℃ = degree cecius = the unit of temperature
E = energy

energy transfer = 能量轉換

J = joule = the unit of energy
W = wok = the unit of power
℃ = degree cecius = the unit of temperature
E = energy

energy transfer = 能量轉換 = 能量由A轉到去B
