An aqueous potassium nitrate solution containing 60.0 wt% kno3 at 80°c is fed to a cooling crystallizer in which the temperature is reduced to 25°c. the solubility chart for kno3 in water is provided. a)is the initial solution saturated? b)at what temperature will the first crystals be formed? c)what is the percentage of kno3 in the feed that will drop out of solution?

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
