Cold, Colder, Coldest
Ice water glows strongly on an infrared thermal camera compared to nearby dry ice and liquid nitrogen.
The height of the fluids in the tubes indicates that pressure is highest where the fluid is moving fastest.
Model Stirling Engine
A model Stirling engine is used to demonstrate energy transformations and heat engines.
A Wire Glows Under Water
A wire glows orange while submerged in water.
The buoyant force on a submerged block is measured along with the force applied by the block on the liquid.
Rock the Boat
A person sits in a boat on a pond holding a rock. If she throws the rock in the water, does the level of the pond go up, stay the same, or drop?
The force applied to a plate and bowl by an airflow are compared. This can be seen as analogous to inelastic and elastic collisions.
