For pure water, the boiling point is 100 degrees Celsius (212 Fahrenheit) at one atmosphere of pressure, and the melting point is 0 degrees Celsius (32 degrees Fahrenheit) at one atmosphere of pressure.

Temperature is also important because of its influence on water chemistry. Warm water holds less dissolved oxygen than cool water, and may not contain enough dissolved oxygen for the survival of different species of aquatic life. Some compounds are also more toxic to aquatic life at higher temperatures.

When water is heated, latent heat of vaporisation is consumed to overcome the intermolecular forces of attraction at a constant temperature.

Water’s high heat of vaporization is important because it helps to moderate the temperature of the ecosystem. When water goes through the water cycle (evaporation, condensation, precipitation), at the stage of precipitation, heat is released, and rain falls.

Steam causes more severe burns. Steam has more energy than boiling water. It possesses the additional latent heat of vaporization. So, when steam falls on skin and condenses to produce water it gives out 22.5 x 105 J/kg more heat than boiling water at the same temperature.

Particles in steam (water vapour) at 373 K (1000C) have more energy than water at the same temperature. This is because particles in steam have absorbed extra energy in the form of latent heat of vaporisation. Thus, steam is more dangerous than water vapour.

Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporisation.

Steam will produce more severe burns than boiling of water because steam has more heat energy than water due to its latent heat of vaporisation and additionally latent heat of condensation. Steam and boiling water can exist at varing temperature but it is only correct to assume here that both are at same temperature.

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. 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.

You may have heard that even when steam and water are technically the same temperature, steam can cause worse burns. Why does this happen? The reason is that steam that burns your skin also goes through a phase change. It becomes water again.

Boiling water is a saturated liquid vapor mixture but steam is either a saturated vapor or a superheated vapor. Steam is hotter than boiling water because steam gets some extra heat i.e latent heat (the amount of heat require to change its state .

immediately get the person away from the heat source to stop the burning. cool the burn with cool or lukewarm running water for 20 minutes – do not use ice, iced water, or any creams or greasy substances like butter.
