The Hand Boiler


 Model Description This is a demonstration of how pressure increases with temperature particularly at temperatures above the fluid’s boiling point.  Warming the bottom chamber beyond the boiling point increases the pressure sufficiently to displace fluid into the upper chamber.  This demonstration should take 5 minutes. Engineering Principle The pressure of a fluid increases as you […]

Boiling Properties


 Model Description This demonstration is designed to show that the boiling point temperature of water is dependent on the pressure.  This demonstration should take 8-10 minutes. Engineering Principle Most students are familiar with the process of boiling water on a stove, but this demonstration will show that the phase change is dependent on both pressure […]
