How can the structure of the vacuum flask minimise energy transfer by conduction convection and radiation?

The flask has a double wall, with no air between the two walls (vacuum)- conduction. The walls are highly reflective silver- radiation. the flask has a small beck that is closed by a stopper or cap-convection.

How does a tight fitting plastic stopper on a flask minimise heat transfer?
It prevents heat transfer by convection as it prevents contact between the surrounding air and air inside the flask. It prevents heat transfer by conduction as it is a poor conductor of heat.
How does silver coating on surfaces of glass walls minimise heat transfer?
being a poor radiator,the two silver faces reflects heat back and forth and reduce heat by radiation.
What is does it mean to save energy?
It means to minimise the the use of energy in the home or business.
What are the advantages of wireless energy transfer?
we can minimise the loss of energy due to practically a non-resistance condition.
How do you minimise energy loss?
You can minimise it by switching all the switches off I ft hey are not in use, don't leave TV on for all day/night if not watching or sat on the computer, don't forget to turn the lights off and don't turn it on when is not dark, don't play with the switches

How do you handle radioactive sources safely?
it is a good idea to wear thick gloves and to stay as far away from the source as possible to minimise the amount of radiation that can reach you

What is meant by structure in c?
A structure is an aggregate of two or more data types, each of which has a unique address within the structure. The structure members need not be the same type. Structures are akin to a database record where members represent the record's fields. The size of a structure is not necessarily equal to the sum of its member sizes. For efficiency, members are typically aligned on an appropriate word boundary which may introduce gaps within the structure. To minimise these gaps, it is best to declare members in order of size, largest first.
