Give reason for your Answer​

Answer 1

Answer:

Yes,she can apply the same method to keep a glass of cold drink cool.

• The wool or the woolen cloth acts as a good insulator of heat which means transfer of heat energy is very low through the woolen cloth.

• This low transfer of heat energy through the woolen cloth helps to retain the warmth of the warm soup because the escape of heat energy is reduced by the woolen cloth.

• Similarly,if she wraps a cold drink glass with a woolen cloth,then the external heat energy will enter very slowly to the glass and the cold drink will stay cool for longer period of time.
