Question

give reasons why steam causes more severe burns than boiling water

Answer 1

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

Answer 2

Steam causes more severe burns than hot water for the following reasons:-

• Steam has more kinetic energy than the boiling water as we all know that gases have more kinetic energy than liquids and steam is at gaseous state and water is in liquid state.

• As the hidden heat or latent heat is used up by the liquid to overcome the force of attraction and to change it's state, so the steam must have more heat than the boiling water.

• Another reason is there the boiling point of water is 100°C and if it is crossed then water will turn into gas which clearly shows that the gas (steam)has more heat than the water.

∴ Steam causes more severe burns than the hot water.
