Question

A 1,000-mL sample of ethanol is tested. Its boiling point is determined to be 78.4°C. What is the most reasonable prediction of the boiling point for a 100-mL sample of ethanol?

Answer 1

78.4°C

Step-by-step explanation:

Boiling point does not depend on the mass of the substance present, only the heat content is a function of the mass or volume of the substance in consideration. If there is 1000 ml of ethanol and it boils at 78.4°C, a 100 ml sample too should boil at the same temperature of 78.4°C.
