What is the diffence between heat and
temperature ?
Answers
Answer:
Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).
Heat:
1. It is a form of energy and measures the total energy of all molecules in the substance.
2. Its unit is joule in Sl and calorie in CGS.
3. Two bodies can be in a thermal equilibrium without having equal thermal energy. Their temperature are equal in case.
4. Flow of heat doesn't depend upon the heat energy contained in bodies in thermal contact.
5. It is a total kinetic energy of all molecules in a substance.
Temperature:
1. It is a measure of degree of hotness or coldness of a body.
2. The unit of degree Celsius or Kelvin or degree Fahrenheit.
3. Two bodies cannot be in thermal equilibrium if they are at different Temperature.
4. Flow of heat depend upon the temperature difference between two bodies. Heat always flow from a body at higher temperature to a body at lower temperature.
5. It is a measure of average kinetic energy of molecules in a substance.
