What is the temperature increase per seconds or minutes on average in a microwave?

Answer 1

Completely depends on what you're heating.

-- If the oven is empty, the air inside stays cool even after it runs.

-- Moist stuff, with water in it, heats the fastest.

-- Stuff with oil or fat in it heats up, but not as fast as water.

-- Dry stuff heats slowly.

-- Larger loads heat up slower than smaller loads.

That's why the shortcut buttons ask you "What substance are you putting in ?" and

"How much of it are you putting it ?", but they don't ask you "What temperature do

you want ?".
