Why is the evaporation of water a physical property rather than a chemical property?
During evaporation the structure of water remain unchanged.
Do evaporation of salt water cause density increase or decrease?
During evaporation the density increase.
Water molecules escape from the water surface during evaporation?
Yes, it is true.
What happens to density during evaporation of salt water?
The density increase.
Does water always evaporate at the same rate in the dark in the light?
Evaporation depends on temperature. During the night evaporation is lowered.
During which process does water gain the most heat energy?
Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
What happens during the evaporation stage of the water cycle?
During evaporation liquid water is transformed in vapors (gaseous water).
Why do you get color with water evaporation?
Particles of dyes can be entrained by water vapors during evaporation.
What state is water in during the process of evaporation?
water vapour
During which process does water vapor in air turn into water droplets as the air cools?
evaporation
Does salt water effect is evaporation?
no. because salt is left as it is in the base during evaporation.
What is a correct numerical set up for calculating the number of joules of heat gained by water?
(mass)(temperture difference)(4.18)
Does water absorb thermal energy during condensation?
No, water releases thermal energy during condensation. It absorbs thermal energy during evaporation, which is why the evaporation of sweat cools your skin.
Why is the evaporation of water a physical property rather than a chemical property?
During evaporation the structure of water remain unchanged.
Do evaporation of salt water cause density increase or decrease?
During evaporation the density increase.
What are the harmful effects in evaporation?
Evaporation during summers leads to drought. During the process of evaporation soil salts move upward making the soil more saline and alkaline, which affect the plant growth. Evaporation of water from plant's leaf (transpiration) leads to wilting if the water lost by evaporation is not compensated by the process of absorption of water by the roots.
What would happen to the speed and energy of water particles during the evaporation phase?
The energy of water molecules is increased to allow evaporation.
