better insulation
It depends entirely on the size of your thermos. They come in different volumes.

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.
An insulator is a poor conductor of energy. For example; Rubber is a poor conductor of electricity Rock is a poor conductor of heat A sponge is a poor conductor of sound.
better insulation
No... the insulation is created by a vacumm and a reflective mirror finish
Different types of insulation are used for soundproofing. Felt insulation, acoustic foam insulation and mineral fiber are the most common types.

There is the insulation of many things. This ranges from houses to thermos.
It prevents heat loss by trapping in the heat.
Insulation prevents objects from conducting heat. It can also be applied around some object to prevent heat from escaping. A thermos is a good example of how insulation can prevent objects from rapid cooling.
It depends entirely on the size of your thermos. They come in different volumes.
Stainless thermos bottles should not be washed in a dishwasher because the high heat and harsh detergents used in dishwashers can damage the vacuum insulation and outer coating of the bottle. This can lead to the loss of insulation properties and the formation of rust on the stainless steel surface.
Either a vacuum (thermos bottle) or air that can't move ... which is just what foam insulation is (tiny bubbles).
A thermos would be better. They are built for insulation to keep temperature as constant as possible for as long as possible. A soda can is just a thin sheet of metal, and heat will be able to flow in and out of the can quite easily.
