Homework Statement



How much heat is absorbed by a person’s hand if 100 grams of liquid water at 100°C is poured on his hand? (Assume the final temperature of the water will be normal body temperature of 37°C)


Homework Equations


dont have any


The Attempt at a Solution


dont have one.

Well, you know the temperature change of the water. You also know the specific heat capacity of water. Therefore, you can figure out how much energy has to be lost by that amount of water in order for that temperature change to occur.

To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
