SAMPLE QUESTIONS

Example Questions From the Test

    • Block A is twice as dense as Block B
    • Block B is twice as dense as Block A
    • They have equal densities because their volumes match
    • Their densities cannot be compared without knowing their shapes
    • It decreases because the gas occupies less space
    • It remains constant because the mass is unchanged
    • It increases because the same mass occupies less volume
    • It becomes equal to the density of the container
    • It increases because its particles move faster
    • It remains constant because its mass is unchanged
    • It decreases because the same mass occupies more volume
    • It becomes equal to the density of the surrounding air
These are 3 of the 16 real questions — the rest appear in the test. No sign-up needed to start.

WHAT THE TEST MEASURES
About This Assessment

Density Quiz - Symptoms and Signs

Test how well you understand density, including mass divided by volume, common units, calculations, buoyancy, measurement methods, and experimental errors. This free quiz contains 16 multiple-choice questions with one correct answer per item. Your total places your density knowledge in one of three clearly defined result bands. It is quick to complete, educational rather than diagnostic, and requires no sign-up.
