Specific Heat, Heating & Cooling Curves

Specific Heat, Single-Phase Heating & Cooling Problems

This video covers problems where you calculate the heat absorbed by a liquid that is being heated up or cooled down without freezing, thawing, boiling or condensing. It also covers problems where liquids of different temperatures are mixed, or a hot object is placed in cool water and allowed to come to equilibrium.

Freezing & Boiling, Heat of Fusion & Vaporization

For most students this is the most confusing part of heating and cooling problems. It makes sense that things heat up as you put heat into them, but how is it that they suddenly plateau and stay at one temperature as they melt or boil away? And why do I care how much heat that takes? Here you go.

Multi-Step Heating & Cooling Curve Problems

This video covers the problem you're most likely to see on your chapter test: multi-step problems where something is heated up and then has to melt or boil. As usual, staying organized is key. You don't want to mix up your specific heat with heat of fusion or vaporization.

Coffee Cup & Bomb Calorimeter Problems

That's not a typo, crazily enough. In this chapter there really is something called coffee cup calorimetry, so named because you could do it using an old-school foam coffee cup. Back in the day when they were styrofoam, before Starbucks (or so I've heard). The trick to the bomb calorimeters is to calculate the heat capacity of the bomb itself.
