A thermos bottle reduces heat loss and gain through a vacuum layer between its inner and outer walls, which minimizes conduction and convection. The shiny surface inside the thermos reflects heat radiation back into the bottle, preventing heat transfer. The tight seal of the bottle also helps to prevent air exchange, further reducing heat transfer.

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.
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 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.
What is the predominant energy transfer that occurs in the thermos bottle?
Conduction is the predominant energy transfer that occurs in a thermos bottle. The vacuum insulation in a thermos bottle prevents heat transfer through convection and radiation, so most of the heat transfer happens through conduction between the inner and outer layers of the bottle.
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.

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.

Where and how does most heat loss occur in a thermos bottle?
Most heat loss in a thermos bottle occurs through conduction and radiation. Conduction happens through the walls of the thermos, which can be reduced by using materials with low thermal conductivity. Radiation occurs through the opening of the thermos, so keeping it sealed tightly minimizes this type of heat loss.
Why you create vacuum in thermos flask?
This reduces heat transport through conduction and convection.
Why the thermos bottle keeps hot water warm for a long time?
A thermos bottle works by minimizing heat transfer through its vacuum-sealed double-walled construction. The vacuum between the walls prevents heat loss through conduction and convection, while the reflective coating on the inner wall reduces heat transfer through radiation, keeping hot water warm for an extended period.
How does a vacuum between the inner and outer walls of a thermos bottle limits heat loss through conduction and convection?
The vacuum acts as an insulator by preventing heat transfer through conduction and convection. In the absence of air molecules, which are poor conductors of heat, thermal energy is primarily transferred via radiation across the vacuum. This greatly reduces heat loss and helps to maintain the temperature of the contents inside the thermos bottle for longer periods.
Why does liquid remain hot or cold for a long time inside a thermos flask?
A thermos flask has a double-walled design with a vacuum layer in between, which minimizes heat transfer by conduction and convection. This helps prevent heat loss or gain from the liquid inside, keeping it hot or cold for a longer time. Additionally, the reflective lining inside the flask reduces heat transfer by radiation.
