Final Temperature

Final temperature is the equilibrium temperature reached in a system after heat transfer or mixing has occurred.  It's often used in thermodynamics to describe the temperature that a system settles at after all processes of heat exchange or mixing have completed.

For example, if you mix two substances at different temperatures together, the final temperature will be the temperature at which they reach thermal equilibrium, meaning they have the same temperature throughout.  This final temperature depends on factors such as the initial temperatures of the substances, their specific heat capacities, and the amount of each substance present.

Similarly, in processes involving heat transfer, such as heating or cooling a substance, the final temperature is the temperature reached once equilibrium is established between the substance and its surroundings.  Calculating the final temperature in a given situation often involves the principles of heat transfer and thermodynamics, such as the conservation of energy and the specific heat capacities of the substances involved.

The formulas for calculating final temperatures in different scenarios do not typically have specific names like laws or principles in physics.  They are derived from fundamental principles such as conservation of energy, heat transfer, and thermodynamics.

Names by Which They are Commonly Known

Mixing of Two Substances  -  This formula is often referred to as the "final temperature after mixing" formula or simply the "mixing formula."
Heating or Cooling a Substance  -  These formulas are part of the broader principles of heat transfer and are often referred to as "heat transfer formulas" or "temperature change formulas."
Mixing of Ideal Gases at Constant Pressure  -  This formula is specific to the mixing of ideal gases and is typically referred to as the "final temperature after mixing ideal gases" formula.

While these formulas may not have specific names, they are fundamental tools used in various fields of science and engineering for calculating final temperatures in different scenarios.
