CONVECTION IN WATER APPARATUS | Perfect for scientific demonstration

CONVECTION IN WATER APPARATUS

• This Convection In Water Apparatus demonstrates heat conduction in a liquid.
• Comprises a large 380 x 300mm borosilicate glass tube 20mm dia. shaped (as per the illustration).
• It has a short glass extension of tubing at the top for filling with water.
• Instructions included.

(Wikipedia excerpt: ..."Convection is single or multiphase fluid flow that occurs spontaneously through the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow.

Convective flow may be transient (such as when a multiphase mixture of oil and water separates) or steady state (see convection cell). The convection may be due to gravitational, electromagnetic or fictitious body forces. Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be identified by clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics...")
