Question

ii. volume measurement (graduated cylinder)
iii. mass measurement (triple beam balance)
iv. thermometer

Explanation:

Step1: Read graduated - cylinder volumes

For a graduated cylinder, read the bottom of the meniscus.

• a. The volume is 8.5 mL.
• b. The volume is 45 mL.
• c. The volume is 82.5 mL.
• d. The volume is 57.5 mL.
• e. The volume is 72.5 mL.
• f. The volume is 6.5 mL.

Step2: Read triple - beam balance masses

For a triple - beam balance, sum the values on each beam.

• a. \(300 + 60+7.5=367.5\) g.
• b. \(400 + 60+7.5 = 467.5\) g.
• c. \(30+7 + 0.25=37.25\) g.
• d. \(400+60 + 7.5=467.5\) g.

Step3: Read thermometer temperatures

For a thermometer, read the value at the level of the liquid.

• a. \(32^{\circ}C\).
• b. (Crossed - out, no answer).
• c. \(9^{\circ}C\).
• d. \(76^{\circ}C\).
• e. \(- 10^{\circ}C\).
• f. \(20^{\circ}C\).
