What Are Some Objects That Minimize Heat Transfer?
The vacuum flask otherwise known as a thermos flask
How does a thermos flask reduce heat loss by radiation?
Vaccum between thermos walls does NOT prevent radiation, however the other forms of heat transfer(convection and conduction) are more or less eliminated. Radiation effect of heat transfer may be reduced by applying a layer of reflective material inside the bootles - to reflect the emmision back inwards.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
How does a thermos flask reduce heat loss by conduction?
Using vacuum as an insulator avoids heat loss by conduction. Heat transfer is minimised by reflective silver surfaces that are applied to the flask. This prevents thermal radiation from entering and escaping the flask.
Why thermos flask does not let the heat escape?
It is especially designed to reduce heat transfer through conduction, convection, and radiation. A vacuum between two layers reduces the heat transfer through conduction and convection; the fact that the surfaces are mirror-coated also reduces losses through radiation.

What is a thermos flask made of?
out of steel
What is the thermo flask?
Thermos flask is a thermos container used to store liquids like any hot drink. The liquid added to thermos flask will retain the temperature even after some time irrespective of external temperatures.
What is inside a thermos?
inside a thermos is flask steel materials, it keeps the thermos for about 1 - 2 days.

What is the other name for a vacuum flask?
A Thermos.

How does the mirror coating prent thermos flask lose heat?
It shiny mirrored surface reflect heat which means the heat will be reduced
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
What do you call the object that keeps water hot for hours?
Thermos flask or vacuum flask.
