define the words:
root pressure
Evaporation
Answers
Answer:
evaporation
Explanation:
evaporation means a substance which is volatile in when it get heat
Root Pressure:Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day.
Evapration:Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other. When a molecule near the surface absorbs enough energy to overcome the vapor pressure, it will escape and enter the surrounding air as a gas. When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling.
