Question

explain which one will cause more severe burn-boiling water at 100°C or steam at 100°C

Answer 1

steam at 100°C. When the state of water changes from its liquid state to gaseous state it gain the latent heat of vaporisation. so the steam we obtain will contain heat energy due to temp 100°c plus the energy due to latent heat..

therefore.. steam at 100°C contains more energy than water at 100°C..
