Vacuum Flask Flashcards
1
Q
Plastic Case
A
Outer plastic case reduces heat loss by conduction
2
Q
Stopper
A
Tight fitting stopper reduces convection conduction and radiation from the top of the flask
3
Q
Support
A
Small support stops the glass from touching the outer container to minimise heat loss by conduction
4
Q
Vacuum
A
Reduces heat loss by conduction and convection only radiated heat can travel through a vacuum
5
Q
Silvering
A
helps reflect any radiated heat back into the flask stopping heat escaping
6
Q
Double Glass Bottle
A
Glass is a good insulator reducing heat loss by conduction. It is also a good to contain the vacuum
