Okay so because of the difference in density a simple method for telling the difference between the two is to put a sample in a container with oil, because water has a higher density than the oil it would sink to the bottom but alcohol on the other hand is lighter than oil and would float on top of the oil.
However with this question I think that what you would do is use the ice to find out what the substance is, it would float on top of the liquid if it were water because the water is denser than ice but the ice would sink if it was alcohol because the alcohol is less dense than ice.
I hope this helps you, good luck : )

Hello is there a specific aliment you have in mind If so I can explain and tell you the answer.
Answer:
Explanation:
The complete reaction equation is given as:
CO + 2H₂ ⇄ CH₃OH ΔH = -90.7kJmol⁻¹
From the reaction equation, we know that:
- the reactants are in gaseous phases. Carbon monoxide(CO) and Hydrogen gas are gases.
- the reaction is an exothermic reaction beceause ΔH is negative. Heat would be liberated to the surroundings in this kind of reaction.
According to Le Chatelier's principle, we know that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
For pressure changes:
A change in pressure affects only equilibrium involving a gas or gases. An increase in pressure will shift the position of equilibrium to the side having smaller volume(or mole) and vice versa.
CO + 2H₂ ⇄ CH₃OH
3 moles of gases 1 mole of gas
An increase in pressure will favor the production of more methanol since we have 3 moles of gas on the left hand side and just one mole of gas on the right hand side.
For temperature changes:
A rise in temperature shifts equilibrium to the direction that absorbs heat and vice versa. Since the reaction is exothermic in the forward reaction, a rise in temperature will favor the forward reaction. This would lead to the production of more methanol gas. A decrease in temperature will favor the backward reaction.
