SUMMARY

Temperature cannot be added between two different bodies; instead, heat transfers from the hotter object to the cooler one until thermal equilibrium is reached, as stated by Newton's Law of Cooling. Temperature is a measure of the thermal state of a body, not a quantifiable entity that can be created or added. The discussion clarifies that while heat can be added to an object, it does not equate to creating temperature. Furthermore, temperature and heat are distinct concepts, with temperature not being a direct measure of heat energy.

PREREQUISITES
  • Understanding of Newton's Law of Cooling
  • Basic knowledge of thermodynamics
  • Familiarity with the distinction between temperature and heat
  • Concept of thermal equilibrium
NEXT STEPS
  • Research the principles of thermodynamics
  • Study Newton's Law of Cooling in detail
  • Explore the relationship between temperature and heat energy
  • Investigate thermal equilibrium and its implications in physical systems
USEFUL FOR

Students of physics, educators teaching thermodynamics, and anyone interested in understanding the principles of heat transfer and temperature measurement.

Can we add temperatures of two different bodies and create more temperature?

No, temperature does not add, The hotter object would get cooler and the cooler object would get hotter.
 
Strictly speaking one cannot "create temperature" anyway. Temperature is a measure of the heat in a body. You can "create heat" or add heat to any object. However, "Newton's law of cooling" says that if two objects, of different temperatures are placed together, heat will flow from the hatter to the cooler body until they have the same temperature.

If by the 'heat in a body' you are referring to energy (it sounds like it since you refer to adding heat) then temperature is not a measure of 'heat'
A white hot spark contains less 'heat' than a cup of hot water. Temperature and energy are different things.
