Answer:
The heat transferred from water to skin is 6913.5 J.
Explanation:
Given that,
Weight of water = 25.0 g
Suppose that water and steam, initially at 100°C, are cooled down to skin temperature, 34°C, when they come in contact with your skin. Assume that the steam condenses extremely fast. We will further assume a constant specific heat capacity c=4190 J/(kg°K) for both liquid water and steam.
We need to calculate the heat transferred from water to skin
Using formula for stream
[tex]Q=mc\Delta T[/tex]
Put the value into the formula
[tex]Q=25\times10^{-3}\times4190\times(373-307)[/tex]
[tex]Q=6913.5\ J[/tex]
Hence, The heat transferred from water to skin is 6913.5 J.
