Why the rate of loss of thermal energy through the walls of the flask

1.	Why the rate of loss of thermal energy through the walls of the flask by radiation is very low
Answer» Answer: Vacuum Flasks work by insulation. So, HEAT cannot enter or leave through conduction. ... The plastic case of theflask is not a GOOD conductor of heat, THUS REDUCING heat loss.
