Explain the first law of thermodynamics and its... - SS1 Physics Heat and Thermodynamics Question

The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed in an isolated system; it can only be converted from one form to another or transferred between systems. This law is based on the principle of energy conservation, which states that the total energy of a closed system remains constant. 

The first law highlights the fundamental idea that energy is a conserved quantity and provides the basis for understanding energy transformations and transfers in various processes. It is essential in fields such as engineering, physics, and chemistry, as it helps in analysing and predicting energy changes and understanding the efficiency of energy conversions.
