The bottom of the meniscus C. The line easiest to see

The edges of the meniscus D. By raising the graduated cylinder

2. The system of measurement that allows people worldwide to compare data is the ___.A. US Customary System C. English Standard SystemB Metric System D. The Scientific Method

3. What is the proper measurement for this 3 beam balance?

27.7 g C. 127.7 g

27.7 mL D. 207 g

4. Name the following piece of lab equipment:

Beaker C. Petri Dish

5. What is the proper measurement for this meter stick?

41.8 cm C. 40 ½ in

41.6 cm D. 40 ½ cm

6. We measured force using an instrument called a

Triple beam balance C. beaker

8. What is the formula used to calculate work?A. Work = mass X accelerationB. Work = force X distanceC. Work = force X mass

9. Sally pushed the 10 kg stroller with 50 N of force and it moved 3 m. How much work was done?

• 150 J
• 50 J
• 500 J
• 30 J

Solubility (g/100g H2O

A. 80.0 g B. 100.0 g C. 102.5 g D. 110.0 g

10. Using the graph below, what is the solubility of KBr at 100oC in 100 g of water?

11. Which ramp requires more force to be used?

The ramp with 4 books

The ramp with 2 books

12. What must a scientist consider when choosing a tool to make a measurement?A. the time of day C. temperatureB. what is being measured D. density of the object(example: length, mass & volume)

13. Is work done if force is applied to an object, but the object does not move?

14. Inclined planes like a ramp __________________  the distance an object travels.
• Decrease C. don’t change
• Increase D. gravity
15. Using ramps such as a wheelchair ramp

A. Changes the amount of work done

B. Changes the amount of force needed

C. Does not change the amount of force needed

16. When you increase the steepness of a ramp you also increase the amount of …

Work done

Force needed

Neither

Both

Identify the correct tool that would be used to measure:

a. Volume is measured by __graduated cylinder_______

b. Length is measured by _meter stick/ruler___________

c. Mass is measured by __triple beam balance_________

d. Temperature is measured by _thermometer_________

18.An irregular object, like a rock, was placed inside a graduated cylinder. How much water was displaced?
• 200 mL C. 280 mL
• 270 mL D. 70 mL

20. A girl carries a backpack at a constant height.  Has she done any work on the backpack?

A. yes B. maybe C. no
