When a cold tire is inflated to a certain pressure and then is warmed up, the pressure increases. This happens because
Air molecules speed up and collide with the tire walls more often
The amount of solute
KCl (pH of 7.0)
increasing the temperature increases the solubility
OH- (hydroxide ion)
The atoms move slowly and are close together
5.0-6.5
plasma
What is the ion formed by bases?
Air molecules speed up and collide with the tire walls more often
The amount of solute
KCl (pH of 7.0)
increasing the temperature increases the solubility
OH- (hydroxide ion)
The atoms move slowly and are close together
5.0-6.5
plasma
Which of these factors does NOT affect solubility?
Air molecules speed up and collide with the tire walls more often
