Which physical property is used to identify matter based on solubility?

• ability to evaporate

• volume

• ability to dissolve

• mass

A student is trying to dissolve 25 grams of sugar in a beaker containing 300 mL of water. The student proposes the following problem:

“What factor would result in sugar dissolving faster in water?”

Which change would most likely cause sugar to dissolve the fastest?

• Decreasing the temperature of the water

• Using larger pieces of sugar

• Stirring the mixture rapidly

• Using less water

Which property cannot be used to classify these objects into more than one group?

• magnetism

• mass

• electrical conductivity

• solubility in water

Which statement identifies a property that could be used to classify these objects into two different groups?

• density can be used the separate objects that sink in water from objects that do not

• magnetism can be used to separate objects that are attracted by a magnet from objects that are not

• solubility can be used to separate objects that dissolve in water from objects that do not

• physical state can be used to separate objects that are solids from objects that are not.
