Physics Question on thermal properties of matter
The material used in the manufacture of cooker must have (k - coefficient of thermal conductivity, s - specific heat of material used)
A
high k and low s
B
low k and low s.
C
high k and high s
D
low k and high s
Answer
high k and low s
Explanation
Solution
A cooking pot should absorb minimum heat and conduct maximum heat A cooking pot should easily transfer heat to its content (high conductivity) and not requiring too much heat to get to the right temperature (low specific heat), because it would reduce efficiency, since you would spend more energy heating the pot instead of the content.
