Concept explainers
The process that would satisfy the conservation of energy principle but not actually be observed in nature.
Explanation of Solution
First law of
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.
Write the expression for first law of thermodynamics.
Here, the change in the internal energy is
It states that the change in the internal energy
A cup of hot coffee left in a cooler room eventually cools off. The heat energy of the coffee is converting into the other form of energy. The process is actually is taking place but not actually be observed in the nature.
