Boiling water is an example of which disinfectant method?

Explanation:
Heat-based disinfection uses high temperature to inactivate microorganisms. Boiling water relies on heat to denature proteins and disrupt cell membranes, rendering bacteria, viruses, and many parasites nonfunctional. That’s why boiling is considered a heat method of disinfection. It isn’t chemical like bleach, nor does it involve radiation or ozone. When using boiling, keep in mind that altitude affects the exact temperature, and some spores may survive if the process isn’t long enough, though for everyday drinking water boiling is typically effective.
