Will two items heat up to the same temperature in the same amount of time in a microwave as just one of those?

Question

items by itself in the microwave?

Answer 1

No, need to out them on a bit longer:D:D

Answer 2

No. I have tried it (not to test this idea, but just general usage of the microwave) with two pieces of frozen bread.

One piece usually takes about 10seconds to defrost. Two take about 20 seconds.

This may only apply to separate, solid objects, and if you are talking about liquids or semi-liquids such as soup, then it might be different.

It has all to do with the amount of energy being spread out of a larger receiving area, eg the bread example, one piece has less area than two pieces so it takes longer to receive enough energy to defrost.

At least that's how I figure it.

Answer 3

2 items will not heat up to same temperature until there heat capacity are equal

even if you put same thing in different quantity then also there final temperature will be different due difference in heat capacity

heat capacity is defined as heat required to raise the temperature of the body by 1degree C.

microwave transfer equal energy(heat) to different things but bcoz of diff heat capacity there temperature become different

Answer 4

The microwave supplies heat to the two items. Both items must be similar (have equal specific heat capacity) in order for them to receive the same amount of energy. Then after that, they must be of the same size (mass and surface area) in order also o to receive the same amount of heat energy. When this is the case, they'll get to the same temperature in a given period of time. However, the time taken for two items to attain a particular temperature in a particular microwave oven would be considerably more than the time required for one of that same item to attain this temperature because the heat being supplied by the microwave oven is constant and in the first case, the items must SHARE the heat, whereas, there's no need for heat SHARING in the second case.
