Heat is the form of energy that flows from a body at higher temperature to a body at lower temperature. It's SI unit is Joule(J). However, it is generally measured in calories(cal).

Temperature is the measure of the degree of hotness or coldness of an object or a body. It is measured using a device known as thermometer, specially the mercury thermometer. There are three scales of temperature. The most common are Degree Celsius(℃) and Degree Fahrenheit(°F). But the SI unit is Kelvin(K).

1. Conduction(in solids)

2. Convection(in fluids)

3. Radiation(in gases).
