Even though the same amount of energy was transferred into both substances from the air, the isopropanol evaporated while the water did not. Why do you think the isopropanol changed phase, but the liquid water did not ... Earlier in the lesson, you observed isopropanol and water drops on a paper towel.HELP HELP PLS

Answer:

The isopropanol evaporated while the water did not because the molecules don't stick together as strongly as the molecules in the water do. The water would need more energy transferred in, in order to evaporate.

Explanation:

The isopropanol evaporates and the water does not because the heat capacity and the latent heat of isopropanol is far lesser than that of water.

  • The latent heat of vaporization is the amount of heat required by a given amount of substance to change its phase from liquid to gas.
  • The latent heat of vaporization of isopropanol is far less than water, so at the same amount of heat, the isopropanol changes phase as it can easily evaporate even if a small amount of heat is provided.
  • Whereas water requires to absorb a lot of heat energy to change its phase, since its latent heat of vaporization and specific heat capacity is very large as compared to isopropanol.
