1.0 INTRODUCTION
Temperature and heat are related to each other but are different concepts. The
temperature of an object is a measure of how hot or cold it is. However, determining the
temperature can be quite subjective, different people will have different perceptions of
what is hot and what is cold. In simple terms, the temperature is said to be the degree of
hotness and coldness. Meanwhile, heat is the transfer of energy from a hot object to a
colder object. More scientifically, the potential for heat transfer by conduction,
convection or radiation. A temperature difference causes heat to flow, just as a voltage
causes a current to flow in a wire. If two objects placed in contact, heat will flow from
the hotter to the colder. When no more heat flows, the object are at thermal equilibrium
and their temperatures are same.
