Yes, it is true.
An increase of the temperature increase the the speed of evaporation.
High temperature and low pressure favors evaporation.
The density of water increase after evaporation.
slower because less water is exposed to the heat, the cause of evaporation.
it could be " how does water evaporate? " or " when is evaporation formed? "
The density increase after evaporation.
The cause is the condensation of water vapors.
A dark pool liner might cause a very small increase in water evaporation, but nothing significant. The dark pool liner will raise the water temp a bit which, in turn, may increase the evaporation rate. But, the evaporation rate is much more dependent upon the air temperature and humidity than on the water temp, so the increase in water temp would only have a very small effect on the overall or net water evaporation rate. Hope this helps ... yes, it will, and it could be a significant increase.
An temerature increase also increase the evaporation.
During evaporation the density increase.
A flashlight does not directly cause water to evaporate. Water evaporates due to heat energy from the surrounding environment, not from light. The flashlight may provide some heat, which could indirectly contribute to the evaporation process by increasing the temperature of the water.
The cause is the continuous movement of water molecules at the water surface.
