Question

which of the following action reduces the heat escaping from the shiny surface of the flask? options:1) Conduction,2)Reflection,3) Convention,4) Radiation.​

Answer 1

Answer:

Radiation

Explanation:

'the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.'

Escape- emission of heat

Answer 2

Radiation reduces the heat escaping from the shiny surface of the flask.

• There are various processes happening inside a flask that make it so effective in trapping the heat but the reduction of heat escaping from the shiny surface of the flask happens through radiation.
• The outer surface of the inner wall and the inner surface of the outer wall are made shiny in this case.
• Radiation does not require a medium as in the case of conduction or convection.
• Hence the correct option is 2.
