Question

Difference between heat and temperature.

Answer 1

The physical property of the substance that determines the hotness and coldness of the substance is known as the temperature. Temperature of the object is responsible for the change in heat of the system. But the temperature and the heat are two different physical quantities.

Complete step by step answer:
The temperature is the physical property of substance. The temperature of the substance is dependent on the kinetic energy of the molecules inside the substance. When the object is heated, the molecules of the objects. As the molecules move in the object with more energy. These molecules collide with other molecules. The collision causes more heat in the object. So, the temperature of the object also increases due to increase in the heat. Heat is the energy change in the substance due to the kinetic energy of the molecule.
Difference between heat and temperature:

Heat	Temperature
It is the form of energy of the substance	It is the property of the substance
Unit of heat energy is Joule.	Unit of temperature is Kelvin ’K’.
It is dependent on temperature for its calculation.	It can be measured using a thermometer.
Heat is the derived physical quantity.	It is the fundamental physical quantity.

Note:
Temperature and heat are two different quantities but they rely on each other. The temperature is the fundamental physical quantity. The unit of the temperature is Kelvin and degree Celsius. The heat is the form of energy, it is the derived physical quantity. The unit of heat is calorie.
