Phase Changes and Heat

In this specific heat learning exercise, students solve 4 problems for either the specific heat of the substance, the amount of heat needed to raise the temperature of a substance a particular number of degrees or the amount of heat...

Clever! Use a clip from the 1997 film, Volcano, to get your chemistry class knee-deep in heat concepts related to lava. In the movie scene, lava flow is stopped in the nick of time. Your class must use calculations to determine if this...

For advanced chemists, this worksheet examines heat change during chemcial reactions. Alkanes are examined first. Learners calculate the energy released or needed during a reaction.

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

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...

When you're hot, you're hot! But, how does something get hot? Young scientists discover the properties of heat energy in an insightful video. The narrator discusses the differences between kinetic and potential energy, how heat transfers...

In this chemistry video, Sal takes a closer look at what happens to the change in enthalpy during a chemical reaction. He points out that, given constant pressure, the enthalpy change becomes the heat added to the system at that constant...

If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...

This learning exercise would make a nifty quiz on the laws of thermodynamics. Nine multiple choice questions assess high schoolers' understanding of energy transfer, specific heat capacity, phase change, fusion, and vaporization. It is...

Take an energetic ride through the phase changes of a water molecule in a compact activity. Young scientists learn about the phases of matter and discover the role of thermal energy in governing phase changes while watching a short...
