Demonstrations
Identifier | Title | Summary | |
---|---|---|---|
T: H - 002 | Sagging Wire | As current is passed through a wire, it heats up and expands |
|
T: H - 003 | Bimetallic Strips | A strip composed of two different types of metals is dipped into a dewar of liquid Nitrogen. Since the metals contract at a different rate, they will curve one direction or the other. |
|
T: H - 005 | Differential Gas Thermometer | A differential glass thermometer shows how liquids expand as they get warm. |
|
T: H - 006 | Expansion and Contraction of Rings using Ball | A metal ring expands when heated. A metal ring contracts when cool. This is shown by whether or not they fit over a metal ball. |
|
T: H - 010 | Lamp with Heat | The wires of a small lamp are placed into an open flame. As the wires heat up, the lamp dims due to the change in resistance of the wire. |
|
T: H - 012 | Low Temperature Behavior | Assorted objects are submerged in liquid nitrogen and smashed |
|
T: H - 014 | Thermal Conductivity Comparison | Rods of various metals have steel balls attached by wax. One end of the rods are heated in the flame of a bunsen burner. Over time, the balls on the rods drop off at different times. |
|
T: H - 015 | Boiling Water in Plastic Bottle | ||
T: H - 016 | Paper with Wood and Metal | ||
T: H - 017 | Davy Safety Lamp | ||
T: H - 018 | Convection of Gases | 2 demonstrations that show air movement caused by differences in temperature. |
|
T: H - 019 | Radiation Transfer with Mirrors | Two parabolic mirrors are used to transfer the heat from one, across the demo bench, to light matches in the other. |
|
T: H - 020 | Laser and Balloon | ||
T: H - 024 | Paraffin Cake and Dissimilar Cylinders | 5 cylinders made of different metals are heated and placed on top of a paraffin cake to demonstrate their differences in specific heat. |
|
T: H - 025 | Dry Ice | Pieces of dry ice are used to help students visualize the P vs. T graph for Carbon Dioxide |
|
T: H - 026 | Regelation of Ice | Due to pressure, a wire melts through an ice cube that remains intact. |
|
T: H - 027 | Gyser | ||
T: H - 028 | Cryophorus | A cryophorus is used to demonstrate that freezing can occur by rapid evaporation |
|
T: H - 030 | Liquification of Air | An air balloon is dipped into liquid nitrogen to create liquid |
|
T: H - 032 | Cloud in a Bottle | ||
T: H - 033 | Boiling Water with an Ice Cube | Water boils due to the presence of an ice cube. |
|
T: H - 034 | Fire Piston | Swift action of the plunger in an air-tight piston causes a tiny bit of cotton to immediately ignite |
|
T: H - 035 | Pipe Pops its Cork due to Heating | Friction generated between wooden slats and a metal pipe causes water inside the pipe to vaporize, thus blowing the stopper out of the end. |
|
T: H - 036 | Hero's Engine | ||
T: H - 037 | Gas Model | ||
T: H - 038 | Dipping Duck | A duck dips into a glass of water continuously. |
|
T: H - 039 | Models of Steam and Gasoline Engines | Two cut-away locomotive engines are available for display |
|
T: H - 040 | Solid Phase Heat Engine | ||
T: H - 042 | Triple Point of Liquid Nitrogen | Nitrogen exists at a solid, liquid and gas at the same time. |
|
T: H - 043 | Boyle's Law with Syringes | Syringes with weights are used to demonstrate Boyle's Law. |
|
T: H - 044 | Thermoelectric Converter | A fan is powered entirely by differences in temperature between 2 beakers of water. |
|
T: H - 047 | Stirling Cycle Heat Engine | Stirling Cycle Engine (working model + cutaway) |
|
T: H - 048 | Holding a Test Tube of Boiling Water | A test tube of water is held near the bottom while the top is tilted into the flame of a bunsen burner. |
|
T: H - 049 | Thermobile | ||
T: H - 050 | Elasticity of Rubber | A stretched rubber band will contract when heated. |
|
T: H - 051 | Steel Wool and Liquid Oxygen | Steel wool immersed in liquid oxygen will easily catch fire |
|
T: H - 052 | Bimetallic Strips with Light Bulbs | A bimetallic strip is used to light one of 2 bulbs, depending on which direction it bends when it is heated. |
|
T: H - 053 | Diatomic Model | A ball and stick model of a diatomic atom |
