Pressure and Temperature Law
Temperature and Pressure What would happen to the pressure in a sealed container (i.e. volume remains constant) if heat is added? Graph the following data: Temperature (K) Pressure (kPa) 129 111 301 242 403 323 501 429 601 517 704 613
Pressure and Temperature Law Pressure increases proportionally as temperature increases, provided volume and amount remain constant. Pressure is directly proportional to temperature (in Kelvins) P T A direct relationship P = kT P = k T P1 = P2 T1 T2
