SUMMARY
When a piston is compressed, the temperature of the gas inside increases due to the work done on the gas, as indicated by the first law of thermodynamics (U=Q + W). In an insulated system, where Q=0, the internal energy U increases solely from the work W done on the gas. The confusion arises from the misapplication of Boyle's law, which assumes constant temperature; however, for an ideal gas, the relationship between pressure, volume, and temperature is governed by the ideal gas law (PV=nRT).
