An insulated bottle keeps coffee hot by convection, radiation and conduction.
Insulated Coffee mugs can be made from many materials, the inner layer is usually made from stainless steel while the outer while can be either stainless steel or plastic. The vacuum design however is what keeps your coffee hot compared to a ceramic coffee mug
Filling the bottle with hot water immediately before use pre-warms the bottle, because heat is transferred from the hot water to the bottle (and in the transfer, the hot water naturally cools a little). This readies the bottle for filling with hot coffee and because the bottle is already pre-warmed, it takes little or no heat from the coffee thus keeping the coffee closer to the temperature that it was when the flask was filled.
I woudn't because the coffee is hot and the bottle is thin. You will burn your hands! Plus, why tempt fate when there are great containers for hot liquids. In fact, I woudn't pour coffee in a stainless steel water bottle because it would burn my hand!

Thermos is a Greek word for "hot."
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system.
any with a heated base will keep it warm as long as you leave it on.

It keeps you warmer, also cooler. When it is hot it will keep you cool, when its cold it will keep you warm It also filters their that coms through your house.
the temperature will rise slightly
a flask is an insolator because if you have coffee,tea or juic it keeps it hot and cold
The building was insulated and the people inside it was hot.
