The GRE Subject Test in Physics assesses knowledge and understanding of undergraduate-level physics concepts and principles.
Thermodynamics and statistical mechanics help us understand how heat, energy, and matter interact, from boiling water to the inner workings of stars.
Whether it's running an engine or keeping food cold, thermodynamics is essential for energy management.
The first law: \( \Delta U = Q - W \), where energy changes equal heat added minus work done.
\[\Delta U = Q - W\]
Refrigerators cooling your food.
Steam engines powering trains.
Thermodynamics explains how energy moves and changes, and why some processes are irreversible.
