Ice decreases in size as it gets colder
Humidity is lower in the freezer air than in the ice cube causing sublimation
H20 only expands when it reaches the freezing point
I never knew ice cubes could shrink. I'll go take a look in my freezer.
One that comes on 10 minutes every hour on the coldest day of the year
One that comes on all day on the coldest day of the year
Bigger the better
Raising/lowering 1 pound of water 1 degree Fahrenheit
Raising/lowering 1 litre of water 1 degree Celsius
Both equal the same
Yes, EnergyStar ratings are applied to all heating units evenly
No, EnergyStar propane units are only better then other propane units, same with oil and geothermal units.
No, the geothermal unit takes electricity to run therefore cannot be as efficient as propane or oil to heat a home
It takes twice the amount of energy to melt ice than raise it 1°F
It takes 7 times the amount of energy to melt ice than raise it 1°F
It takes half the amount of energy to melt ice than raise it 1°F
It takes 144 times the amount of energy to melt ice than raise it 1°F
The home at 72°F (21°C) and with a relative humidity of 50% feels warmer
The home at 72°F (21°C) and with a relative humidity of 30% feels warmer
Both would feel the same
Anywhere from 10:1 to 15:1
About the same
Anywhere from 2:1 to 6:1

Simply by not heating your house, the temperature would be the same throughout.
Open all the registrars wide open.
Turn the fan on continually.
Increase the temperature on the thermostat
