Below are sample questions representative of the exercises included on this worksheet and related 6.33 Substances and Characteristic Properties skill assessments:

Problem 1Difficulty: Mastery

A student compares two samples. Sample X: density 1.05 g/mL at 20°C Sample Y: density 1.05 g/mL at 20°C But X boils at 90°C and Y boils at 100°C at 1 atm.

Which statement best describes the most reasonable conclusion?

AX and Y are likely different substances because boiling point differs under the same pressure, even though density matches.

BBoiling point is not characteristic for liquids.

CX and Y must be the same because density matches exactly.

DX and Y must be the same because both are liquids.

Solution & Explanation:Boiling point at a fixed pressure is characteristic. Different boiling points provide strong evidence of different substances.

Problem 2Difficulty: Mastery

A student says, “A pure substance always has the same properties, so it doesn’t matter how you measure them.”

Which statement best corrects this?

AIf results differ, the substance stops being matter.

BEven for pure substances, measurements must be made carefully and under stated conditions; errors or changing conditions can make the measured value differ from the true characteristic property.

COnly mixtures require careful measurement.

DMeasurement skill never matters because properties measure themselves.

Solution & Explanation:Characteristic properties are consistent under set conditions, but poor technique or changing conditions (temperature, pressure) can produce incorrect measured values.

Problem 3Difficulty: Mastery

A student has two liquids and measures density for each at 20°C. Both are 0.80 g/mL. The student wants a second property that is also characteristic and easy to measure safely.

Which choice is best?

AMeasure boiling point while also recording pressure (or measuring at the same pressure) to compare a second characteristic property.

BMeasure how quickly the liquid splashes when shaken.

CMeasure the height of the liquid in the container.

DMeasure the container’s mass.

Solution & Explanation:Boiling point can distinguish liquids if measured at the same pressure. Height/splashing/container mass are not characteristic of the substance itself.
