Answer:
A thermos flask has double walls, which are evacuated and the vacuum bottle is silvered on the inside. The vacuum between the two walls prevents heat being transferred from the inside to the outside by conduction and convection.

Answer:
A thermos flask has 2 layers:
1. A metal inner layer
2. A plastic outer layer
Explanation:
The reason behind the 2 layers is because:
1. The vaccum between them is a really good insulator, making sure that the temperature remains constant.
2. The plastic layer is also an insulator and it has the same function.
