If only conductive heat loss was significant for a house then by what percentage

I think the conductive heat loss is proportional to the DIFFERENCE
between the inside and outside temperatures.  In other words, if it's the
same temperature inside and outside, then no matter what that temperature
is, no heat flows through the walls of the house in either direction.

You said it's 20° outside, and you turn the thermostat down from 70° to 60°.
So you'd be reducing the DIFFERENCE between the inside and outside
temperatures from 50° to 40°.

From 50 to 40 is a decrease of (10/50) = 20%.  So your heat loss ... and
the amount that gets added to your heating bill ... becomes 20% less for
each hour that the inside and outside temperatures stay like this.

it will allow the potato to cook evenly because the metal skewer gets as hot as the water/heat your cooking/baking it in which will result in the potato being very  light and fluffy because your not over cooking the the outside of the potato while under cooking it in the inside.

hope this helps!(please mark brainliest)
