You're asking a tricky question! There's no single answer because solubility depends on both the substance and the solvent.

Here's why:

* Solubility is specific: The solubility of a substance (like salt or sugar) is how much of it can dissolve in a particular solvent (like water) at a given temperature.

* Temperature matters: Solubility changes with temperature. Some substances become more soluble as the temperature increases, while others become less soluble.

To give you a meaningful answer, you need to tell me:

1. What substance are you interested in? (e.g., sugar, salt, oxygen gas, etc.)

2. What solvent are you using? (e.g., water, alcohol, oil, etc.)

Once you provide this information, I can tell you which substance is more soluble at 10 degrees Celsius.
