Does putting hot water in a thermos bottle before you put hot coffee in it help to keep temperature?
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.

What is the function of lid lock in thermos bottle?
The lid lock in a thermos bottle helps to securely seal the bottle to prevent leaks and maintain the temperature of the contents. It also helps to prevent accidental spills and keeps the lid from opening unexpectedly.

What is a thermos bottle an example of?
A thermos bottle is an example of a container with double-walled insulation that helps maintain the temperature of its contents, keeping them hot or cold for an extended period of time. It utilizes a vacuum layer to reduce heat transfer through convection and conduction, thus preserving the temperature of the liquid inside.
Why is the inner of the thermos bottle is silvered?
The inner lining of a thermos bottle is typically silvered to minimize heat transfer by reflecting thermal radiation. The reflective silver coating helps to maintain the temperature of the liquid inside the bottle by reducing heat loss or gain through radiation.
How does a plastic stopper in a thermos bottle control heat transfer?
A plastic stopper in a thermos bottle helps to control heat transfer by minimizing conduction through the opening, where heat can escape or enter. The plastic acts as an insulator, reducing heat loss or gain from the contents inside the thermos. This helps to maintain the temperature of the liquid for a longer period.
Who invented the thermos bottle?
Joshua Fears.
How and where does the most heat loss occur in a thermos bottle?
The most heat loss in a thermos bottle occurs through conduction, convection, and radiation. It mainly happens at the opening of the thermos bottle where there is direct contact with the surrounding environment, as well as through the materials used in the construction of the bottle that are not efficient insulators.
