The Three Types of Heat Loss!

Home | Sales Brochure | How to make a Thermos! | Three types of heat loss!

Convection:The lid stops the heat/cold from escaping and the pink fiberglass keeps the heat/cold in and circulating and therefore it keeps the liquid hot or cold! 

Conduction: Keeps the kinetic energy from particle to particle with no net displacement of the particles. The particles are bouncing off of each other and the barriers[insulation, newspaper and Duct tape] and conducting the heat/cold back into the bottle.

Radiation: The insulation, newspaper and Duct tape radiates the heat/cold back into the bottle. They act as a barrier to keep the heat/cold in the bottle.

I love Science!!
