Adding water to acid that's kind of dangerous
Answer:
about the same
Explanation:
Thermal energy is constant at a certain temperature in general. The energy is denoted by 
Where,
is the Boltzmann constant
T is the absolute temperature
Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.
Thus,
The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.
