Intermediate Cooking Skills Quiz
1) Take a 20-oz Pyrex measuring cup, and fill it halfway with room temperature water. Place it in a 1000W microwave oven, and heat at full power for 30 seconds. Will the water be:
a) nearly unchanged in temperature
b) hot but not boiling
c) completely boiled away
d) superheated liquid, so that when you take it out, it explodes and causes 2nd-degree burns over your hand and forearm
e) spilled all over when the cup broke because you shouldn’t microwave Pyrex
f) pink because the cup’s red lettering melted and mixed with the water
2) Now remove the cup (wearing a long-sleeved oven mitt in case the above answer was “d”) and replace with 2 16-oz Pyrex cups, each half-filled with room temperature water. Heat at full power for 30 seconds. Will the water be:
a) the same temperature as the previously heated cup
b) not quite as hot, since the microwaves had to divide their energy across twice as much water
c) completely boiled away
d) only halfway boiled away
e) spilled all over again with 2 broken Pyrex cups — didn’t you learn your lesson the first time?
3) Now take another 16-oz Pyrex cup, fill it with room temperature water, and place it in an oven set at 300 degrees F. Wait for 20 minutes, and remove the cup. Will the water be:
a) spilled all over the floor because you forgot to put on the mitt before grabbing the cup
b) hot but not boiling
c) completely boiled away
d) spilled all over when the cup broke because you shouldn’t put Pyrex in a 300-degree oven
4) Now replace the cup with two 16-oz Pyrex cups, each half-filled with room temperature water. Wait for 20 minutes, and remove the cups (after putting on the oven mitts, of course). Will the water be:
a) the same temperature as the other oven-heated cup
b) not quite as hot, since the oven heat had to divide its energy across twice as much water
