What is the predominant energy transfer that occurs in the thermos bottle?
thermal energy
How does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped
Is a mug a bad heat insulator?
Yes. Out of paper, plastic, glass, a thermos, a mug, and Styrofoam, the mug held the least heat in. The thermos is the best.
What Are Some Objects That Minimize Heat Transfer?
The vacuum flask otherwise known as a thermos flask
What keeps the contents of a thermos flask hot or cold?
The thermal insulation used round the container holding the food. This is normally an evacuated, mirrored, double walled glass flask with an insulated stopper.
What is stopper in the thermos?
Its reduces evaporation, and something else i dont know! :)

What is the job of a thermos?
To keep hot liquids hot and cold liquids cold by minimizing heat transfer between the inside of the thermos with the outside.

Yes. Out of paper, plastic, glass, a thermos, a mug, and Styrofoam, the mug held the least heat in. The thermos is the best.
What processes of heat transfer are affected with thermos flasks?
Conduction, convection and heat radiation.

What is a thermos bottle made out of?
Traditionally, Thermos bottles used borosilicate glass for the vacuum insulator, with a plastic or metal envelope. Modern Thermoses are typically made entirely of steel.
Does the dial on the thermos water bottle control the lid speed?
YES
How do you insulated thermos?
Um......your question is worded oddly, but the way an thermos is insulated is by having a vacuum between it's two flasks. The vacuum causes heat transfer to reduce greatly.
How do you use plastic cups to make a homemade thermos?
tape two opening mouth together
