Unformatted text preview: strongly and others weakly. 1. These particles move around (i.e. have kinetic kinetic energy). 1. The kinetic energy of particles increases with temperature. The particle model TIME FOR A S Temperature and energy Evaporation occurs when the particles in a liquid escape to form a vapour. Evaporation can occur at any temperature but it occurs most rapidly at a liquids boiling point. The particles that escape take some energy from the remaining particles and so the temperature of the liquid falls. What is evaporation?...
