WORST heat conductor to BEST is Option b) glass, concrete, copper
Explanation for correct option:
- Thermal conductivity is defined as the ability of the material to conduct heat.
- The value of thermal conductivity for copper, concrete and glass is 398 W/m•K, 2.25 W/m.K and 0.8W/m.K respectively.
- As it is evident from the values that copper is a best conductor, then comes concrete and glass is the worst of all.
- Therefore, icecube on the copper surface melted first and that on the glass surface melted at the last.
Explanation for incorrect options
- a)copper, glass, concrete
- c)copper, concrete, glass
- d)concrete, copper, glass
Above given are all incorrect options because they are not arranged from worst to the best as described in the explanation for the correct option.
Final Answer
Option b) glass, concrete, copper is arranged from worst to the best.
