Woala, Vanessa, Hi! You have said that your question deals with physics though I am led to believe that it is very biological in nature. Actually it's the way that you look at things. Life and death are of course, in a way, physical!! Any way, jokes apart, let me try and remove your paranoia about these little mischievous creatures. Bacteria are not always harmful as we are led to believe. Fermentation is a splendid example. Of course, most of the time these little devils can be quite a pain in the whatever! Firstly, there are medicines which are technically termed as anti- biotics which can make these creatures vamoose---they prevent their multiplication in the human body, topically or atopically by making them deceased. Though temperature affects their survival in so far as there exists something known as optimal temperature for their survival and flourishing, killing them is not exactly whether you can reach a critical killing temperature or not. If you want more technical information you can try giving the search-word "antibiotics and functioning" in some search- engine like web-crawler or alta-vista-digital. Of course, nowadays, scientists have their hands full as drug-resistant bacteria are evolving. That is why doctors will forbid you from using anti-biotics for a prolonged period of time. It's the bacteria's way of saying: So there! The last sentence obviously should have convinced you that there is no single effective way of making your house-hold bacteria-free. It's just not possible--neither practically nor theoretically. All that you can hope for is that your surroundings don't become a breeding ground for the dangerous breeds of these micro-organisms. Hygiene and sanitation are the only feasible ways. Of course, since I happen to be an under-grad, you may not be too convinced with my answer. Moreover, I believe if you want a far more technical and convincing answer you should post your question indicating biology as your area of interest. Sincerely, Aninda
