My oven knows when it reaches 400 degrees. If I open the oven door, presumably the temperature drops, but my oven will still show 400. Is the temperature a lie?

Answer 1

Yes, the temperature of the air drops. The thermistor/thermocouple measuring the temperature is behind the metal hull of the oven though and not just dangling in the air in the middle, and it will take a couple seconds at least before it starts showing a lower temperature.
