Question

18. Specific heat of substance ‘A’is 3.8 Jg 'k' and Specific heat of substance B is 0.4 Jg 'k?
i) Which of two is a good conduction of heat?
ii) Which one would be more useful on car radiators?​

Answer 1

Answer:

i) B is a good conductor as the specific capacity of B is lower than A so less heat is required to raise the temperature of 1 g of B by 1 K than the heat required for A.

ii) A would be more useful on car radiators as will extract much more heat without much change in the temperature.

HOPE THAT IT WAS HELPFUL!!!!

MARK IT THE BRAINLIEST IF IT REALLY WAS!!!!
