College Chemistry Instructor Guide

(PS-3803A)

College Instructor edition with 36 experiments covering introductory and general chemistry topics.

Ethanol & Acetone Interaction

Lab Summary

Use an absolute pressure sensor and stainless steel temperature sensor to determine and relate the heat of vaporization of substances to the interactions between molecules.

Theory

Students determine and relate the heat of vaporization of substances to the interactions between molecules.

Method

Students gain experience conducting the following procedures:

  • Studying the molecular interaction of ethanol and of acetone by monitoring their vapor pressure as a function of temperature.
  • Using pressure and temperature sensors.
