Hand Boiler

Instructions / Notes:

• Use the warmth of your hand on the flat base of the demo to "boil " the liquid inside.

Concepts Conveyed:

• Methyl chloride in a glass tube is used to demonstrate temperature and pressure relationships of gas.
• As temperature rises in the closed container, pressure rises as well.
• The "boiling" of the liquid is the result of pressure differences between the lower and upper chamber of the boiler.
• Expanding gas bubbling in the liquid gives the appearance of boiling.

Faculty Notes:

• It's recommended you order the demo camera with this demo so it can be seen by all students.
