What does the symbol T represent in physics?

Temperature is what the symbol T usually stands for in physics. It measures how hot or cold something is and relates to the average kinetic energy of the particles in a substance. In common equations like the ideal gas law, PV = nRT, temperature is the T and is used in Kelvin in physics problems. The other quantities have different standard symbols—voltage is V, power is P, and resistance is R—so T doesn’t represent those. Time, meanwhile, is typically shown as t, not T, in physics formulas.
