Solution
a)
The two ways by which the physical state of matter can be changed by the following two methods -
- By increasing or decreasing the temperature.
- By increasing of decreasing the pressure
b)
c)Raising the temperature of water increases the kinetic energy of surface molecules, hastening the rate of evaporation.Moving air channels displaces saturated air away from the liquid, effectively lowering concentrations of water immediately above the liquid therefby hastening the process of evaporation.
