How Vacuum Flask Prevents Heat Loss?

How a Vacuum Flask Prevents Heat Loss

The science behind how a vacuum flask prevents heat loss
The vacuum flask was invented in 1892 by Sir James Dewar. It is a double-walled flask with a vacuum between the walls. This prevents the transfer of heat from the inside of the flask to the outside. The vacuum flask is made of two glass or metal walls with a vacuum between them. The vacuum is created by boiling water in a small container and then attaching the container to the flask. The boiling water creates a vacuum in the container, which sucks the air out of the flask. This leaves a vacuum between the walls of the flask, which prevents the transfer of heat from the inside of the flask to the outside.
