This simulation allows students to make observations about how particle motion changes as the overall temperature of a liquid changes.

An indexing page for the HyperPhysics site. The page contains a concept map of links to a variety of other pages which discuss concepts related to heat engines. All pages contain informative graphics and excellent explanations.

Explore heat, temperature, and the conduction of thermal energy through different materials.

This lesson will give a brief introduction to calculating heat (Q) by using mass, specific heat, and change in temperature. It is 3 of 4 in the series titled "Calculating Heat."

Slide the temperature gauge and see what happens to the movement of the molecules.

Source of weather maps, forecasts, images, and data for the world. Maps include temperature, radar, visibility, wind, heat index, wind chill, humidity, and dew point.

Over more than a century, the global average temperature warmed 1.5F (0.8C). Learn the science of why this has happened, and what the future holds.
