Question

What is the temperature of melting ice? Why do we use nested foam cups? why does the mass of the water decrease? The heat of fusion of water and the heat of vaporization of nitrogen are given below Complete the the by showing the problem set-up (with unrounded answer) used to convert the given values to units of J/g, cal/mol and J/mol. Write the rounded answer in the Hank provided. How much heat is needed to melt 65.77 g of ice at 0 degrees C? in cal? inj? How much heat is needed to vaporize 1.72 moles of nitrogen? in cal? inj?

Explanation / Answer

Melting point is the temperature at which state of the matter changes from solid to liquid at atmospheric pressure.

And at the melting point both the states solid and liquid exist in equilibrium. On going from liquid to solid it is referred as crystallization point or freezing point.

For ice the melting point is 0 oC
