EXAM - Vacuum Flask Flashcards
1
Q
Vacuum
A
Vacuum reduces heat loss by conduction and convection only radiated heat can travel through a vacuum
2
Q
plastic case
A
outer plastic case reduces heat loss by conduction
3
Q
Tight fit stopper
A
reduces conduction convection and radiation from the top of the flask
4
Q
Support
A
Small support stops the glass from touching the outer container to minimise heat loss by conduction
5
Q
Double glass bottle
A
Glass is a good insulator reducing heat loss by conduction and is also good to contain the vacuum
