Steam from boiling water causes more damage on the skin than does boiling water because
water has a high specific heat
steam has latent heat of fusion
the steam is at a highter temperature than the water
steam brings heat more easily by convection

My school the answer is D, steam and boiling water are both at the same temperature (100°C), but the steam cariies more heat energy because of the latent heat of vapourization. Pls correct your answer.
Myschool please stop giving wrong answer. I known body is absolutely perfect.
The answer to that question is D not c.
I refer all the jambite to read a topic called heat change in physic
Myschool, believe the correct answer to be C and not D.
The correct answer is "steam is at a highter temperature than the water"
Explanation....
Steam has more energy than boiling water. ... 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. Steam has more energy than boiling water. Therefore, burns produced by steam are more severe than those produced by boiling water.
The correct answer is B. steam has latent heat of vaporization.
When steam comes into contact with skin, it condenses into water, releasing its latent heat of vaporization. This process causes a significant amount of heat energy to be transferred to the skin, leading to more severe burns.
Latent heat of vaporization is the energy required to change a liquid into a gas. In the case of steam, this energy is released when the steam condenses back into water.
The other options are not correct:
A. Specific heat capacity refers to the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius. While water does have a high specific heat capacity, this is not the reason why steam causes more damage.
C. Steam and boiling water are typically at the same temperature (100°C at standard atmospheric pressure).
D. Convection is the transfer of heat through the movement of fluids. While steam can transfer heat through convection, this is not the primary reason why it causes more damage than boiling water.
B is actually correct 💯 😅
I see you once change the answer.. BUT THE CORRECT 💯 ANSWER IS B
When steam condenses on the skin, it releases a large amount of latent heat (vaporization), in addition to the heat it already has at 100°C.
