Compare Properties Before and After Practice Test

Comparing the substances before and after mixing, a student mixed baking soda (white powder) with water (clear liquid). The mixture became a cloudy liquid, but no bubbles formed and the temperature stayed 22°C. Which conclusion is best supported by these property changes?​

The table compares properties before and after mixing sugar and water.

Before mixing:

• Sugar: white crystals, Solid, 22°C, no smell
• Water: clear, Liquid, 22°C, no smell

After mixing:

• Sugar water mixture: clear, Liquid, 22°C, no smell, no visible crystals

How can you tell this is a physical change and not a chemical change?
