When bacteria are boiled the heat energy from the boiling water transfers through to the cells of the bacteria causing the water inside them to begin boiling as well. This increases the pressure inside the cells until they bursts, killing the bacteria. However boiling water will not have this effect on all bacteria.
Water should be boiled for at least one minute to effectively kill bacteria.
we use bacteria (called starter) to make yoghurt from boiled milk.
when liquid is boiled it convert into steam and become vapour
Because the bacteria can be harmful to health and boiling will kill them.
It coagulates.
it runs away
It evaporates.
It changes to a gas (steam).
When water is boiled is transformed in a gas; the reverse process is called condensation.
Water should be boiled for at least one minute to effectively kill bacteria.
Pretty much nothing.
it will make holes
