Question

Why water vapour is more dangerous then boiling water

Answer 1

Answer:

water vapour is more dangerous than boiling water because when water evaporate it need more temperature to become vapour which is 100 ° but water need just 40° to boil thus water vapour cause more Sevier burn than boiling water

Answer 2

Water vapor burns are worse than the water burns.

Explanation:

When a substance vaporizes, this process itself takes energy too.

A large amount of energy is required to actually change the phase (boil, for example) of a substance like water. This is a physical property called “heat of vaporization”,

The boiling point of water is 100 degrees Celsius.

At this temperature the water will begin to change from the liquid state to the gas state. In order for this change to take place, additional energy is required. In fact, every gram of liquid water requires 540 calories of heat energy just to convert it to steam. This is called the Heat of Vaporization.

During the conversion process, temperature does not increase. It is, therefore, possible to have both liquid water and steam that exist at 100 degrees Celsius. While they both would exist at the same temperature, the steam would have a lot more heat energy due to the additional 540 calories per gram of heat energy that has been absorbed.

This is why steam burns are worse than the water burns.

it’s different for every substance.

Heat of fusion is the energy that’s required to actually overcome the attraction between molecules and make them leave their close-knit liquid family and fly off into the atmosphere as a far-flung gas. Water has an especially high heat of fusion because of the hydrogen bonds between water molecules— it takes a lot to separate them.

So, water molecules which have been vaporized contain a high amount of kinetic energy. When they condense and change back into a liquid, they give off this energy (heat) to the object they’re condensing on. This can be a LOT of energy. So, if steam condenses on you, you’re the unhappy recipient of a LOT of heat energy. Hence, bad burns.
