Question

The householder installs cavity wall insulation. What would happen to the time taken for the temperature to fall between points A and B?
The time taken decrease
The time taken increases
The time taken stays the same

Answer 1

Answer:

the answers the correct one is: the time increases

Explanation:

When an insulating material is placed in the cavity of a wall the thermal conductivity of the system increases, therefore the temperature changes take longer.

             P= dQ / dt = K A dT / dx

when placing insulation the value of k is less

When reviewing the answers the correct one is: the time increases
