Vapor Pressure and Boiling

The heat of vaporization, pressure, and boiling points are the topics covered in these calculations. Four questions give some of the variables and ask for the missing information. You could use this worksheet to work through as a whole...

Explore the properties of solutions with a lab activity. Chemistry fans determine the boiling point of water, add salt to create a solution, and then repeat the process four more times. They design their own data table and then graph the...

Humans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

Diagrams bring barometers to light in this PowerPoint. Several slides explain the structure and function of this apparatus. The relationship of air pressure to the processes of evaporation and boiling are also explained. This would be an...

This extensive collection of slides begins with diagrams of molecules undergoing evaporation, progresses through methods of measuring pressure, demonstrates how to perform pressure calculations, and then explores the temperature-pressure...

Wow! This is a nifty presentation for teaching high school chemists about the heating curve. It displays a graph for temperature vs. heat added, then enters the curve itself. The final slide identifies each part of the curve. Notes are...

Vapor pressure is the focus of this chemistry video. Sal explains that, when molecules are "sticking together" a substance takes on a liquid, or a solid form. But when kinetic energy is increased, the molecules are forced apart and a...

A problem from a chemistry textbook is posed on the screen. Sal solves the problem which attempts to calculate vapor pressure using the Ideal Gas Law. The rate of evaporation of water given a certain volume, temperature, and pressure is...

What is temperature, and why are there three different temperature scales? Young scientists learn the true nature of temperature with an informative video. The narrator discusses all three temperature scales and the relationship between...

How do chemists use solubility data? Chemistry scholars learn the usefulness of solubility curves and how they are generated. The seventh part in a series of 14 discusses the solubility rules, plotting solubility data, and how pupils can...
