When bacteria are exposed to heat, their cell membranes start to break down, and their enzymes become denatured. This means that the bacteria can no longer function properly and eventually die. It's like trying to run a car without gasoline - it just won't work!
For example, when you pasteurize milk, you're killing off any bacteria that might be present. This is why pasteurized milk is safer to drink than raw milk. The heat from pasteurization is like a sterilization process that eliminates any potential threats.
But heat isn't just limited to cooking - it's also used in cleaning and disinfection. When you wash your hands with hot water and soap, you're using heat to kill off any bacteria that might be lurking on your skin. It's like a mini sterilization process for your hands!
