The modern scientific name for heat is

Thermal energy is the part of the internal energy of a thermodynamic system in equilibrium that is proportional to its absolute temperature and is increased or decreased by energy transfer.

This is: physically, heat is understood as the energy that is transferred from one system to another or from one body to another, and this is a transfer linked to the movement of molecules, atoms and other particles.

In this context, it is important to keep in mind that bodies have no heat, bodies have internal energy. When a part of this energy is transferred from one system or body to another that is at a different temperature, we talk about heat.

So, the transfer of heat will occur until the two systems are placed at the same temperature and the so-called thermal equilibrium is reached.

scientific laws are the result of testing theories and proving them to be facts.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
