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

Depends. Some ovens show the temperature setting not the actual temperature. Even if the oven claims to show the actual temperature, the display itself depends on what the programmers of the computer inside the oven want to display. In some cases, it might be a time averaged temperature. And any temperature measurement device has latency since it may not react to quick changes in temperature. And temperatures may not drop much (or at all) if the door is only opened briefly.

Bottom line is that, unless the oven is expensive and designed for professional use, the temperature display might only be somewhat accurate.
