When did you find the highest difference in the recorded temperature?
The official highest recorded temperature is now 56.7°C (134°F), which was measured on 10 July 1913 at Greenland Ranch, Death Valley, California, USA.
Can the difference between two temperatures be negative?
If you were asked “How much higher is the boiling point of X than the boiling point of Y”, then −750 degrees would be the right answer.

How warm should the air be coming out of the vent?
The air coming out should be 14 to 20 degrees cooler than the air flowing in. Move the thermometer to a vent in each room or area of your home. If any of the vents are much colder or warmer than another, there may be a problem with the ductwork, or the distance may be too great from the blower.
