Practice Problem: Colligative Properties
What are colligative properties? They're properties of a solution, such as freezing point depression and boiling point elevation, which differ from the pure solvent. Let's do some calculations regarding these concepts!

Practice Problem: Calorimetry and Specific Heat
In calorimetry experiments we measure heat transfer. Say we take a hot piece of metal and put it in some cold water, and measure the rise in temperature of the water as the system equilibrates. Can you use this information to calculate...

Khan Academy: Chemistry: Chilling Water Problem
Figure out how many grams of ice is needed to lower the temperature of water by sixty degrees in this video lecture. The lecture explains how the ice absorbs heat from the water to lower the temperature. Using the specific heat of water...
