Overview

Thermodynamic processes describe the change of a system from one state to another. The First Law (ΔU = Q - W) governs these transformations.

Fun Facts

"In an isothermal process, all heat added to the system is converted into work."
"Diesel engines use adiabatic compression to ignite fuel without a spark plug."
"The expansion of a gas into a vacuum is a free expansion process where no work is done."

Formula: ΔU = Q - W
