ANSWER
Heat transfer is minimized because of:
1. The vacuum between the two walls, rubber, glass, cork and air do not allow the loss of heat by conduction.
2. Cork in the neck of flask and the cup over it prevent loss of heat by convection.
3. Heat cannot be lost by conduction or convection because of vacuum between the two walls.
4. Heat loss is also minimized by radiation, by making outer surface of inner wall and inner surface of outer wall silvered. The inner wall is a bad radiator and the outer wall is a good reflector of radiation.
