Question

part g 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) part h though you add heat, the temperature of boiling water remains constant because it takes energy to break hydrogen bonds it takes energy to break covalent bonds water has a constant boiling temperature

Explanation:

For Part G:

• (a) Molecules colliding with varied angles and speeds is related to the kinetic - molecular theory. Faster - moving molecules can escape as vapor during sweating.
• (b) Weak hydrogen bonds mean less energy is needed to break them, allowing water to evaporate during sweating.
• (c) Water having more energy at the body surface is also relevant as it aids evaporation. All three factors contribute to cooling by sweating.

For Part H: When boiling water, heat energy is used to break hydrogen bonds between water molecules instead of increasing the temperature until all hydrogen - bonded water molecules are in the vapor phase. Covalent bonds within water molecules are not broken during boiling.

Answer:

Part G: E. (a), (b), and (c)
Part H: it takes energy to break hydrogen bonds
