Glucose does not dissociate when dissolved in water. I<span>t simply converts from solid to the aqueous form:
</span> <span> Glucose is an organic compound. Generally organic compounds are formed by covalent bonds which do not dissociate into ions. Ionic compounds like NaCl, KCl dissociates.</span>
Increasing temperature inside a closed container - keeping everything constant will make pressure increase. Because the energy being held by the molecular (the gas molecules) rises, the container may expand meaning the volume increases.
