The difference is the unusable energy.
Usable energy refers to energy that can be easily converted or transformed into a form that can be readily used to perform work or provide power. This can include electricity, mechanical energy, or heat energy that can be efficiently utilized in various applications. Ensuring energy is in a usable form is crucial for powering our homes, transportation, and industries.
Temperature is a measure of the average kinetic energy of the particles in a substance. Thermal energy is the total kinetic energy of all the particles in a substance. Heat is the transfer of thermal energy between two objects due to a temperature difference.
Thermal energy and temperature difference are related because thermal energy is the total energy of the particles in a substance, while temperature difference is the measure of the difference in average kinetic energy of particles between two substances or within a substance. In simpler terms, thermal energy is the total energy present in a substance, while temperature difference is the measure of how much hotter or colder one substance is compared to another.

No, heat is not a measure of total energy. Heat refers specifically to the transfer of energy between systems due to a temperature difference. Total energy takes into account all forms of energy an object possesses, including potential, kinetic, and internal energy.
usable energy changes, while total energy does not
In any transfer of energy or conversion of energy from one form to another, the total amount of energy does not change. The total amount of usable energy, however, always decreases.
No. It tends to decrease.

Activation energy is not part of the overall difference in energy between reactants and products in a chemical reaction; instead, it is the energy required to initiate the reaction by overcoming the energy barrier. The overall energy change, or Gibbs free energy change, is determined by the difference in energy between the reactants and products. While activation energy affects the rate of the reaction, it does not alter the total energy difference associated with the reaction itself.

Not at all. The First Law states that energy is conserved - you can't create energy out of nothing, or make it disappear. The Second Law distinguishes usable from unusable energy, and states that the amount of unusable energy will increase over time - but the total (usable plus unusable energy) will still remain constant.Not at all.

Temperature is a measure of the average kinetic energy of particles in a substance, while thermal energy is the total internal energy of a system due to the motion of its particles. Essentially, temperature is a specific measurement of energy, while thermal energy encompasses all the energy within a system.
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. Heat, on the other hand, is the transfer of thermal energy between two systems due to a temperature difference.
