Steam at 100 ∘C100\ ^\circ\text{C}100 ∘C causes a more serious burn than the same mass of water at 100 ∘C100\ ^\circ\text{C}100 ∘C. Which statement explains this?
The steam is at a higher temperature than the water when it touches skin
The steam has a higher specific heat capacity than the water at 100 ∘C100\ ^\circ\text{C}100 ∘C
The steam spreads out over a larger area of skin than the water does
The steam transfers energy as it condenses as well as when it cools down
