In case of a burn you would use?
The first question many students asked us was:
Melting and boiling point of water is not fixed and there many factors which influence it like the pressure applied, presence of impurities. So it possible to raise, lower the melting point of water.
Now coming back to the question. We need to find the material which is going to absorb more energy.
Specific heat of water if 4.2J/g while the latent heat of ice is 330J/g.
But converting ice to water at [email protected]!! will require !!330J!!.
So Ice at !!10C!! appears much colder than water at [email protected]!!
