Heat comes from heat sources such as Fire, Light, Wind , Friction by rubbing of 2 objects against each other .


Temperature is the characteristic of Heat . Temperature indicates of heat intensity . High temperature indicates hot sensation . Low temperature indicates cold sensation . Temperture is denoted as T measured in degree o

Below is a table of some Standard Temperatures

Standard Temperatures Degree C Degree F Degree K
Frozen temperature 0 oC
Boiling temperature 100oC
Room temperature 25oC

Temperature measurement systems[edit]

There are 3 Temperature measurement systems namely

Conversion between these systems of temperature can be done as shown below

Convert from to Formulas
Fahrenheit Celsius °C = (°F – 32) / 1.8
Celsius Fahrenheit °F = °C × 1.8 + 32
Fahrenheit kelvin K = (°F – 32) / 1.8 + 273.15
kelvin Fahrenheit °F = (K – 273.15) × 1.8 + 32

Heat and matter[edit]

Observations indicate that

  • Dark and thin matter is easy to absorb heat energy than light and thick matter . Dark and thin clothes dry faster than bright and thick clothes
  • Heat travels from high temperature to low temperature . Heat always travel from hot water to cold water
  • Heat transfer through 3 states of matter Solid, Liquid and Gas through 3 phases Heat conduction, Heat convection and Heat radiation
