How do thermos work?
A thermos works with principle of Physics that vacuum is a pure insulator of heat. Thermos is made of two containers separated by a vacuum space which acts as an insulator of heat. Also the surface of thermos will be glassy which in turn helps in reduction of heat loss.
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.
How do you heat a thermos?
I put hot water in the thermos and let sit for a few minutes until inside gets hot.
How the rate of heat transfer is reduced?
rate of heat transfer between two bodies can be reduced by providing insulation between the two. e.g. As in thermos flask. where the insulation prevents heat flow from liquid/tea stored inside the flask to outside atmosphere
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
Where does the word thermos come from?
Thermos is from the Greek word 'thermos' meaning 'heat'.
What is the difference between a heat insulator and elctrical insulator?
an electrical insulator blocks the flow of electricity (like the rubber around power cords that stop you from getting electrecuted) and a heat insulator block the flow of heat (like a thermos)
What does therm mean in Greek?
thermostat, thermometer, thermos, hypothermia
Why sides of thermos bottle are silvered?
Silver is a great heat and light reflector. That means if you store cold water in a thermos, the heat from outside cannot get into the thermos easily because the heat is reflected by the silver color of the thermos.
What is a good slogan for a thermos called heat saver?
Save the heat in heat saver the only thermos that saves all the heat put into it Save heat with heat saver
This is having to do with heat?
Thermos

What would be a better calorimeter a thermos or a soda can?
A thermos would be better. They are built for insulation to keep temperature as constant as possible for as long as possible. A soda can is just a thin sheet of metal, and heat will be able to flow in and out of the can quite easily.
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 is the greek or latin root word for thermostat?
The Latin root for the word thermosphere is thermos: meaning heat.
What is a heat-resitant container?
it is a thermos. It stores heat and Coldness. That is if you get a good one.
How the rate of heat transfer is reduced?
