Temperature Change and the States of Matter

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

Diagrams bring barometers to light in this PowerPoint. Several slides explain the structure and function of this apparatus. The relationship of air pressure to the processes of evaporation and boiling are also explained. This would be an...

A somewhat strangely formatted slide show that contains multiple examples of matter types. The classification and state explanations given would be useful as practice of substance identification and the heating curve may prove to be...

The three states of matter are the focus of this chemistry video. Sal uses the example of a water molecule and explains in great detail the forces present that allow the molecule to change between a liquid, a solid, and a gas. Of course,...

Have you ever wondered why cities in cold climates put salt on the roads to help keep ice from forming? In this chemistry video, Sal explains why the introduction of salt molecules suppresses, or delays, the formation of ice crystals...

What is temperature, and why are there three different temperature scales? Young scientists learn the true nature of temperature with an informative video. The narrator discusses all three temperature scales and the relationship between...

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

This lab serves as a short introduction to both changes in state and air pressure/the gas laws. The students will heat a small amount of water in an aluminum can. They will then invert it in a bucket of cold water and crush the can using...

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...
