Explain how a woolen sweater keeps you warm in winter.

• Wool fibers repel cold air and moisture

• Wool fibers conduct heat away from the body

• Wool fibers trap air, creating a layer of insulation that retains body heat.

• Wool fibers absorb heat and release it slowly

How does double glazing reduce heat loss in a house?

• By allowing more heat to escape through the windows

• By increasing the conductivity of the glass

• By creating a vacuum between the two panes of glass

• By creating a barrier between the inside and outside of the house, trapping air between two panes of glass which acts as insulation.
