Answer:
evaporation is the process in which water change into vapors
Answer:
Answer 1... A..)Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
The rate of evaporation is affected by,
(1) Temperature: Evaporation increases with an increase in temperature.
(2) Surface Area: Evaporation increases with an increase in surface area.
(3) Humidity: Evaporation decreases with an increase in humidity.
(4) Wind speed: Evaporation increases with wind speed.
B) Evaporation causes cooling.
Because in evaporation the water changes form liquid to vapour state so the vapour of water causes the surface to becomes cool.
Evaporation causes cooling because during evaporation the particle of the liqued absord energy from the surroundings to regain the energy lost during evaporation. the absorbtion of heat from the surrounding makes the surrounding cool.
answer 2.....There are five known phases, or states, of matter: solids, liquids, gases, plasma and Bose-Einstein condensates. The main difference in the structures of each state is in the densities of the particles
Answer 3....Melting point:- The melting point of a substance is the temperature at which it changes state from solid to liquid.
Freezing point:- The Freezing point is the temperature of a liquid at which it changes its state from liquid to solid at atmospheric pressure.
Boiling point:- The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
