Problem 105P

Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 kJ per gram of water evaporated. Estimate the mass of water that must evaporate from the skin to cool a body by 0.50 °C, if the mass of the body is 95 kg and its heat capacity is 4.0 J/g °C. (Assume that the heat transfer is 100% efficient.)

Step-by-Step Solution:
Step 1 of 3

Solution 105P

In this question it has been given that,

mass of body = 95kg,

Heat capacity =  4.0 J/g °C

Temperature = 0.50 °C

Here we have to calculate the mass of water that must evaporate from the skin to cool a body by 0.50 °C,

Now, the heat absorbed by body can be calculated as

q = mass heat capacity  q...
