Or should it be the other way around, because hotter water evaporates easier than cold water?
I know this sounds stupid, so just hear me out.
I use an evaporative cooler and add normal room temperature water. Someone told me to add cold water to get better results. I intuitively thought that indeed cold water will produce colder air.
But as we all know evaporative coolers cool air by using the air to evaporate water which takes away heat from the air. So, we need the water to evaporate to cool the air. But we know that hotter water evaporates easier than cold water.
So, should it not be the case that colder water will actually not evaporate as efficiently and hence not produce cooler air than in case of hotter water?
For what its worth, i tried both and could not feel any noticeable difference, but of course it was nowhere close to a controlled experiment. So, I would appreciate an answer about what does the physics predict about what would happen?
