a cylinder contains hydrogen at a pressure of 500000 Pa when the gas is at a temperature of 16 ° C. Subsequently, the cylinder pressure gauge indicates a pressure of 5500000 Pa. What is now the gas temperature?
Use the fact that, in this situation P/T =constant, where P = pressure and T = absolute temperature.
500000/(273+16) = 550000/T
T = (55/50)*289 = 317.9K
or T = 317.9 - 273 = 44.9°C
.
