What is Heat?
• The energy transferred from one object to another
because of a temperature difference between
them is termed heat.
• The unit of heat is Joule (J)
• Heat energy always moves from:

What is temperature?
•
•
•
•
Temperature is the amount of heat in the system
The units for temperature are:
Degree Celsius (°C)
Kelvin (K)

Temperature conversions between the
temperature scales
kelvin
degree Celsius conversions
kelvin = degree Celsius + 273.15
degree Celsius = kelvin - 273.15
