The relation 'PV = nRT' shows which law of physics:
Correct answer: D. Ideal Gas Law
- A. Charles Law
- B. Avogadro's Law
- C. Newton's Constant
- D. Ideal Gas Law
Explanation
PV = nRT is the ideal gas law, which combines Boyle's law, Charles's law and Avogadro's law into a single equation of state. Charles's law on its own says only that volume is proportional to absolute temperature at constant pressure.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
