Steam at 100 ∘C100\,^\circ\mathrm{C}100∘C causes a more severe burn than the same mass of boiling water at 100 ∘C100\,^\circ\mathrm{C}100∘C. Which is the best explanation?
Steam gives out extra energy to the skin as it condenses into water
Steam particles take in energy from the skin as they condense into water
Steam particles are at a higher temperature than the water particles
Steam particles are larger, so they transfer more energy to the skin
