# Physical Science--Chapter 3 Test: The Characteristic Properties Of Matter

18 Questions | Attempts: 101  Settings  Test taking strategy advice! 1. Read all questions carefully and try to eliminate choices that are obviously wrong. 2. If stuck on question, skip it for now and come back later (answer each Q eventually). 3. In essays, think before you write and be sure to answer the question. 4. Please ask for clarification if something is unclear to you. 5. Take your time and do your best. You’ll never regret doing the best that you can.

• 1.

• 2.
A test tube containing a clear, colorless liquid and a thermometer was left out in the air in a room whose temperature was 23° C. The temperature was read at regular intervals, and the results are shown in the graph.
• 3.
A 15 cm3 sample of a liquid was heated and its temperature was recorded as a function of time.  The graph of figure 1 was plotted from the data.
• 4.
Two students, Alice and Sunil, were each given two test tubes containing different amounts of clear, colorless liquids.  They heated the liquids with identical burners.  The temperatures of the liquids were read at regular time intervals, and the results were plotted on the graphs below.  Alice and Sunil live in different cities.

. Imagine you’re an astronaut and on a trip to the moon you discover a huge pile of some strange slimy, glowing, orange substance that is too big to move, even with your spaceship’s crane.  It makes a strange sound and smells like tacos.  You name it blork.
• 6.
How could you find the density of the blork, even though it’s too big to move?
• 7.
What assumptions would you be making about blork if you went ahead with this procedure?
• 8.
Why do warm fluids (air, water, etc) rise?  Explain, using the word density.
• 9.
How would you define ‘characteristic property’ – and why are they useful?
