Question

which factor is important in making it possible to cool yourself by sweating? think carefully! (a) molecules collide with varied angles and speeds. (b) hydrogen bonds are relatively weak. (c) water has more energy at the body surface. both (a) and (b). (a), (b), and (c).

Explanation:

Sweating cools the body through evaporation. Molecules in water (sweat) collide with varied angles and speeds (a), allowing some high - energy molecules to escape as vapor. Hydrogen bonds in water are relatively weak (b), which also aids in the evaporation process as it is easier for water molecules to break away from each other. Water near the body surface has more energy due to heat transfer from the body (c), further promoting evaporation. All these factors contribute to the cooling effect of sweating.

Answer:

E. (a), (b), and (c)
