The difference in volume in a graduated cylinder when an object is added is called....

• displacement method

• density

• mass

• weight

Answer explanation

using a graduated cylinder to find the volume of an irregular solid is called water displacement.

What is the volume of the ring? (new volume - old volume)

• 64 mL

• 68 mL

• 4 cm³

• 4 mL

Answer explanation

Initial volume is 64 mL. After ring is put in, final volume is 68 mL. So 68-64 = 4 cm³ (because it's a solid, 1 mL of a liquid is the same as 1 cm³ for a solid.

What is the volume of the cylinder?

• 10 mL

• 10 cm³

• 8 cm³

• 5 mL

Answer explanation

Initial volume is 19 mL. After ring is put in, final volume is 29 mL. So 29-19 = 10 cm³ (because it's a solid, 1 mL of a liquid is the same as 1 cm³ for a solid.

What is the volume of the water in this graduated cylinder?

• 10 mL

• 15 mL

• 12 mL

• 14 mL

Answer explanation

Read at the meniscus. 12 mL

The mass of 10mL of water at room temp would be

• 10L

• 10Kg

• 10m

• 8.5g

• 10g

Answer explanation

For fresh water 1ml of volume will have a mass of 1g, SOOOO 10 mL of water has a mass of 10 g

Convert 17 m to cm:

• 0.17 cm

• 0.017 cm

• 1,700 cm

• 170 cm

Answer explanation

meters (m) to centimeters (cm) is two hops to the right. So you move the decimal two places to the right and add two zeros to the number 17 becomes 1700cm

Convert 300 meters to centimeters:

• 3000 cm

• 0.3 cm

• 30,000 cm

• 3 cn

Answer explanation

meters (m) to centimeters (cm) is two hops to the right. So you move the decimal two places to the right and add two zeros to the number 300 m becomes 30,000 cm

490,000 g =____ kg

• 490

• 49

• 4,900

• 0.49

Answer explanation

grams (g) to kilograms (kg) is three hops to the left. So you need to move the decimal three places to the left.

490,000 g becomes 490 kg
