In frozen meal manufacturing, frozen meat pies are prepared by first baking them at 220oc, then freezing them cryogenically, using liquid nitrogen, to −20oc.
a) what is the temperature difference from baking to freezing the meal?

b) liquid nitrogen is −196oc. what is the difference in temperature between the liquid nitrogen and the frozen meal temperature (−20oc)?

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8
