​5.1a Heat and Temperature

Heat (Thermal) Energy - Energy that is being transferred from one material or source to another in order to cause a temperature or phase change.

Enthalpy of a reaction is the heat energy of that chemical reaction.
  
Temperature and absolute temperature 

•         The temperature of a substance is related to the average kinetic energy of its particles
•         Therefore, at some point the average kinetic energy of the particles should reach zero
•         At this , point the temperature would not be able to decrease further
  • This point is called absolute zero  and is equal to -273^oC

Absolute Temperature
    • Measured in units of kelvin (K)
    • Absolute Temperature is defined to be zero kelvin at absolute zero.
    • Converting degrees Celsius to kelvin can be done with the equation below:

T(K)= θ(^oC) + 273
