A safety value of steel tank will open when the internal pressure exceeds 1.00x10^3mmHg. It is filled with methane at 24.15 Celsius and 0.994 atm. If the temperature increaes to 100 Celcius. Will the safety valve open? Conversion of T into absolute temperature: ? Calculation of P (P1/T1=P2/T2): ? Pressure comparison: ? Please help!
The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure P and temperature T is expressed by the Clausius-Clapeyron equation. lnP2P1=ΔHvapR(1T1−1T2) where P1 and P2 are the vapor pressures at the absolute temperatures T1 and T2, respectively, ΔHvap is the heat of vaporization of the substance in joules per mole, and R is the ideal gas constant, which is equal to 8.3145 J/(mol⋅K)....
