It is size dependent. There are bacteria - single cells - visible with the naked eye. If the bacteria is smaller than the microwave wave leingth, then no - if it is larger yes, it wil bounce around as if it were in a poodle. I really loved that dog, too. [V]
Actully, sticking stuff in the microwave will excell the growth of bacteria, because it will heat all of the surrondings, and any bacteria that is already their will grow at rapid speeds, but if you heat something up that was in the fridge, or freezer, there wont be much bacteria because the cold will either slow down (fridge, or completely stop (freezer) the growth of bacteria
Oh, so does that mean that over 100 degree C. every bacteria is killed?
There are two different issues.The vast majority of bacteria are killed at 100°C, but there are a small group of exotic bacteria (called thermophiles) that are quite happy to live at temperatures up to 140°C (maybe even higher),
Is there any low temperature that is so cold it kills these "thermophiles" not including, 0° Kalvin?
So if i used freezing point depression would that mean that bacteria could survive in water that is about -30° Celsius?
