How does the first law of thermodynamics affect your life?
It makes all of my transportation possible, heats/cools my buildings, cooks my food and explains global climate effects.
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy.
