Walls and Insulation

Question 1

How does the thickness of a wall affect the rate of cooling?

Answer 1

Thinner walls take a shorter time to cool down

Rate of temperature drop is greater if walls are thinner

Question 2

How does thermal conductivity of walls affect the rate of cooling?

Answer 2

Walls of higher thermal conductivity will cool down faster

The rate of temperature drop is higher if thermal conductivity is higher

Question 3

What is thermal conductivity?

Answer 3

How quickly energy is transferred through a wall with area of 1msquared, thickness of 1m, temp. difference of 1 degree
