The liquid-solid-vapor triple point of a pure substance is Tt=283 K and Pt=0.05 bar. The molar densities of the liquid and solid phases are ?l=22 kmol/m3 and ?s=26 kmol/m3, respectively. The molar enthalpy change of sublimation of the solid at the triple point is ? ?H sv=6.22 kJ/mol and the molar enthalpy change of vaporization of the liquid at the triple point is ? ?H lv=5.65 kJ/mol. Calculate the melting temperature of the solid at a pressure of 10 bar, assuming that the ratio ? ?H sl=?? Vsl is temperature independent, where ? ?H sl is the molar enthalpy change of melting and where ?? Vsl is the molar volume change of melting.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
