Answer: A. Make A Guess
Explanation: A hypothesis is a statement you test, first you have to come up with an idea or theory to test, which would then become your hypothesis.
Answer:
The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
Explanation:
For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.
So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.
Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
