Sophia: Changes in Freezing Point and Boiling Point

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

Have you ever wondered why cities in cold climates put salt on the roads to help keep ice from forming? In this chemistry video, Sal explains why the introduction of salt molecules suppresses, or delays, the formation of ice crystals...

Some fish not only survive but thrive in Antarctic waters. Learn their secret in a lesson in an informative video about the freezing point of the salty sea water as well as the antifreeze proteins in the species' circulatory system.

Here is a fun display that will help your physical science fanatics understand freezing points and crystal formation. Use rock salt, sparkling water, and ice to create a -10¡C bath. Place full bottles of soda into the slurry to supercool...

Understand what happens when raising or lowering the boiling or freezing point of a solution by adding solute. [14:00]

This video tutorial reviews the freezing point and boiling point constants of water. [1:19]

Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.

This lesson will provide examples of how to identify an equilibrium shift due to a change in concentration of either reactants or products.

A guided screencast which explains how to identify a shift in equilibrium based on changes in volume or pressure. [6:15]
