Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
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.
Students determine and relate the heat of vaporization of substances to the interactions between molecules.
Students gain experience conducting the following procedures:
Erlenmeyer flask, 250-mL
Graduated cylinder, 50-mL
Hot plate with magnetic stirrer and stirring bar
100% Ethanol (C2H5OH) - 50 mL
Acetone ((CH3)2CO) - 50 mL
Rubber stopper, 2-hole
Glycerin - 2 drops
Water - 1200 mL
This experiment may require software and an interface for data collection.
