Energy remains constant.
First law of thermodynamics was proposed by Helmholtz in 1847. He stated that:"Energy can neither be created nor can be destroyed , but it can change from one form to another form"
That probably refers to the First Law of Thermodynamics, also known as the Law of Conservation of Energy. It means that the total amount of energy in a closed system (for example, in the Universe) can't increase or decrease.
The total energy of an isolated system will never increase nor decrease. Any increase in energy in a closed system (one where no mass crosses the system boundaries) must come by the addition of that energy from outside via heat or work. Likewise any decrease can only come via heat leaving the system or work being done by the system on its surroundings.
No, it won't increase nor decrease. Energy can't be created or destroyed (First Law of Thermodynamics). On the other hand, the amount of USEFUL energy will usually decrease in energy transformations (Second Law of Thermodynamics).
According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.
The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another, which aligns with the principle of conservation of energy. The second law of thermodynamics introduces the concept of entropy, indicating that while energy is conserved, it tends to disperse or spread out, leading to a decrease in usable energy for doing work. Together, these laws illustrate that energy transformations are governed by conservation principles while also acknowledging the inevitable increase in disorder within a closed system.

When a gas expands at high pressure, it does work on its surroundings to overcome the external pressure. This work done by the gas results in a decrease in its internal energy, leading to a decrease in temperature as per the first law of thermodynamics. So, the gas cools down as it expands at high pressure.
Those would basically be the First and Second Laws of Thermodynamics. The First Law (energy conservation) states that the total energy can not be increased or decreased. The Second Law imposes some limitations about what conversions are possible.
The fact that usable energy is always lost in an energy transfer is due to the second law of thermodynamics. This law states that entropy, or disorder, tends to increase over time in a closed system, leading to the loss of usable energy in the form of heat.
