What are the advantages of having a roof with a lower thermal conductivity? Which of the following two is correct

Less energy is needed to heat the house
The roof is a better insulator
The roof is less likely to leak
The rate of energy transfer by conduction is greater
Weather will have a greater effect on the temperature of the house

less energy is needed to heat the house

the roof is a better insulator

a material with a low thermal conductivity transfers energy slowly, and may be used as a thermal insulator.

Explanation:

hope this helps! The rate of energy transfer by conduction is greater

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
