Before a trip from New York to Boston, the pressure in an automobile tire is 1.7 atm at
278 K. At the end of the trip, the pressure
gauge reads 1.9 atm. What is the new Celsius temperature of the air inside the tire?
(Assume tires with constant volume.)
Answer in units of ◦C.

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
