That's a bit of a tricky question! It seems like you're asking about a mixture of sulfur, sodium chloride (table salt), and sand. Here's why it's a physical change:

* No new substances are formed: You're just combining these materials together. Sulfur, salt, and sand retain their original chemical identities.

* Separation is possible: You could use physical methods like filtering, evaporation, or magnetism to separate these components back out.

Think of it like this: Imagine making a beach-themed salad! You're combining different ingredients, but you haven't changed their fundamental nature. You could easily pick out the grains of sand, the salt, and the sulfur.
