Because sweat on body evaporates and this heat of evaporation is absorbed from body rendering it cool . In this process energy is conserved if sweat and body are considered as system so no external energy is transferred. If we wipe sweat off then it can't evaporate and absorb heat from body so this way body can't cool.
14 Explain in terms of conservation of energy why sweating cools your body, even though the...
1) In your own words, explain why companies might decide to collude (work together) even though it is illegal in the US. (hint: How will it benefit them?

HoMEWORK FOR INTRODUCTION TO HEAT AND TEMPERATURE 1. Approximately what is human body temperature on the Celsius temperature scale? Which is better at transferring heat, water or air? How does this fact explain the length of time it takes the temperature probe to reach thermal equilibrium with the air or water it is in? 2. 3. What effect does the evaporation of water have on the object from which it is evaporating? When has your body experienced this effect? 4....

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...
