If it was negative 75 degrees outside and the heat failed in a house, how long would it take the inside of that house to get below freezing?
When I was a kid, maybe 10 or so (circa 2002-2003), I was talking about Antarctica with my dad and he said "if your heater broke, you'd die" there. 75 below is a typical temperature in the dead of winter in interior Antarctica. By the way, the house in this scenario is a typical house as would be constructed in the Northern United States (the buildings in Antarctica are probably much better insulated)
Negative 75 degrees Fahrenheit (negative 59 degrees Celsius)

Depends on insulation and thermal retention of your house.
Typically, you are talking 60 minutes, less if the wind is blowing.

It depends on the quality of insulation, the actual outside temperature, the style of the house, the exact outdoor temperature, the amount of wind blowing.

Depends on several factors: How well the house is insulated. How high the ceilings are. How big the house is. How many people are in the house. Whether they are doing any cooking by a method which hasn't failed.

No way to answer this with the information provided. It could be a few minutes, it could be a few hours.
Needed:
Wind speed outside
Humidity
Total volume of the house's interior
Total mass of all the house's contents
Are the people staying inside?
Total surface area of the entire house including the roof
Total R-value of the roof
Total R-value of walls
Total U-value of windows
Once you have that information you could come up with a solution. As it stands, impossible to say.

Too many variables to say 'how long'. But I think a safe bet would be less than 24 hours.

Depends on the size of the house, the temperature inside at the time the heat fails, the effectiveness of the insulation, etc. At that sort of temperature extreme, it wouldnt take long, though.

Depends on how well it's insulated and how much air leaks there are. No way to just give you a simple number.
