Took a a test and got it correct .... ——-The solubility curve for a gas would start higher and curve downwards as temperature increased
The solubility of a substance is depends upon the temperature Temperature can change the solubility of a solute.
solubility, degree to which a substance dissolves in a solvent to make a solution (usually expressed as grams of solute per litre of solvent).
The chart is missing so there is no way to tell what does the graph show.
Yet, I can help you because I can explain the status of each statement of the choices. As you will see there is only one possibility..
1) Temperature can change the solubility of a solute.
Yes, temperature definetely can, and mostly do, modify the solubility of a solute.
You can search any chart of solubility and will find that.
I can give you two examples:
a) Sodium chloride: dissolve some spoons of salt in a cold water until you can not dissolve more. Then, heat the water, you will find that more salt will get dissolved, proving that the temperature of the solution increases the solubility of sodium chloride.
b) Carbon dioxide gas: the soft drinks have CO₂ molecules dissolved in it.The higher the temperature of the soft drink the less the amount of CO₂(g) that can be dissolved. That is why the soda bottling plants cool the beverage before adding the CO₂(g).
Hence the solubility of a substance is depends upon the temperature Temperature can change the solubility of a solute.
