4. Difference between heat and temperature

In our day to day life, we usually get confused between the terms heat and  temperature. We hear the word temperature often in weather forecasts, but do we know that,

 

 

Heat is one form of energy transferred between objects, materials or systems with different temperatures. Generally, the heat transfers from higher to lower temperature. It is also known as Heat energy or Thermal energy.

 

Heat is the transfer of thermal energy, whereas temperature is a property that the object exhibits.

Parameters to be compared	Heat	Temperature
Definition	Heat is defined as the flow of energy from hotter to cooler objects..	The measurement of hotness or coldness of a substance.
Property	It flows from hotter to cooler objects.	The temperature rises when we heat, and falls when we cool.
Particle	Heat depends not only on the temperature of the substance but also on how many molecules are there in the object.	It is related to how fast the atoms or molecules move or vibrate within the substance and determines the direction of heat flow.
Measures	The total kinetic energy of the molecules in the substance.	The Average kinetic energy of the molecules.
SI Unit	Joule	Kelvin
Units	Joule, Calorie	Kelvin, Fahrenheit and Celsius
Symbol	\(Q\)	\(T\)
Measuring Instrument	Calorimeter	Thermometer
Working ability	It has the ability to do work.	It is used to measure the degree of heat.
