The mass remain unchanged.
Yes, when water evaporates, its mass does not decrease. The water molecules simply change from a liquid state to a gaseous state, but the total mass of the water remains the same.
no the mass remains the same
The concentration of solutes in water increase.
When water evaporates, the water molecules gain energy from the surroundings to overcome intermolecular forces and escape into the air as vapor. While the water loses mass during evaporation, this mass is not lost but rather converted into the potential energy of the water vapor. Therefore, the total mass and energy of the system (water and surroundings) remains constant, demonstrating conservation of mass and energy.
Temperature and Pressure.
The law of mass conservation is generally valid.
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
Increase of mass from water. Actually increase in mass is the result of increase in organic matter instead of water.
Fanning increase the rate of evaporation.
More water molecules gain energy and can escape from the liquid.
The amount of water in the ocean temporary decrease.
The law of mass conservation remain valid.
