(a) During evaporation, liquid particles gain energy from their surroundings. This increased energy allows them to overcome the intermolecular forces holding them together in the liquid phase. They gain enough kinetic energy to escape into the gaseous phase. Therefore, the kinetic energy of the particles in the liquid increases.
(b)
- Temperature: A higher temperature means the particles have more kinetic energy, leading to a faster rate of evaporation.
- Surface area: A larger surface area allows more particles to escape into the gaseous phase, increasing the rate of evaporation.
