Energy Changing Processes
In this video Paul Andersen explains how energy can enter and leave a system. The amount of energy a substance can receive through heating or lose through cooling is measured using the specific heat capacity. Phase changing energy from...

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...

There is much more to calories than what you see on a nutrition label. The 34th lesson in a 35-part video series explains calories on a scientific level. The comprehensive video gives examples and shows how to measure calories of a given...
Crash Course
Calorimetry
When the chemists who designed hand warmers were working, they had to consider how much heat they could give off to keep people warm — and not burn anyone in the process. How is this heat given off in a chemical reaction measured?...
