125g of ethanol gas at the boiling point 78.4oC is cooled to a liquid with final temp of 50C. Draw a rough estimate of the cooling curve that would be observed.

Question 4

4.

Ethanol (C2H6O) boils at 78.4C, has a ΔHvapor of 40.5 kJ/mol and a ΔHfusion of 5.0 kJ/mol. Specific heat C2H6O(liq) = 2.419 J/g oC. How much heat is lost if 125g of ethanol gas at the boiling point 78.4C is cooled to a liquid with final temp of 50C?
