If I place a quart jar of water that has been tested positive for bacteria into a 1000w microwave, how long will it take to kill 100% of the bacteria.
Thank you, Dell
Thank you, Dell
There is a small enough amount of water in the cloth that the mw will boil it off quite quickly. Not the same as a containerful.wxrocks said:I was under the impression that bacteria (a majority) would be killed by microwaves as well. I often see kitchen tips that include throwing your washcloth in the microwave after washing dishes for about 45 seconds to kill bacteria on the cloth. It does help with the smell.

Welcome to PhysicsForums! So you're just a baby boomer . Many of us on here on PF are of the same generation.dellbertt said:I am 60 years old and I have bacteria in my water...
Perhaps you are thinking microwaves damage the bacteria directly.dellbertt said:I was under the impression microwaves killed bacteria without needing to boil.
Please reread the references (underlined text) listed in my last post. Microwaves don't blast anything. They induce heating by vibration of the molecules. Your http://www.romill.cz/index.php?lang=eng&show_dir=36 also acknowledges the thermal effect.Panda said:It is possible to use high energy microwave pulses to sterilise without heating and this is done commercially for packaged foods

Using High Peak pulsed (*microwave) power causes little heating of the medium but still effectively kills off bacteria.
When bacteria are exposed to microwaves, the water molecules inside the cells begin to vibrate rapidly due to the electromagnetic radiation. This causes the temperature of the bacteria to rise, ultimately leading to their death.
No, microwaves can only kill some types of bacteria. Some bacteria have thicker cell walls that can resist the effects of microwaves, while others have protective spores that can survive the heat. It is important to follow proper food safety guidelines to ensure all bacteria are killed.
Yes, microwaving food can kill harmful bacteria if done correctly. It is important to follow proper cooking and reheating guidelines to ensure the food reaches a high enough temperature to kill any harmful bacteria present.
No, bacteria cannot develop resistance to microwaves as they do not have the ability to adapt and evolve in response to such a quick and intense change in temperature.
No, it is not recommended to use a microwave to disinfect objects or surfaces. The heat from the microwave can cause the object to become very hot, which can lead to burns or even start a fire. It is best to use proper disinfectants or hot water and soap to clean and disinfect objects and surfaces.
