Science Note Cards Test DEC 4th

Question 1

Definition of Density

Answer 1

The relationship of how much mass is in a given volume

Question 2

What are the units for density?

Answer 2

g/mL and g/cm3

Question 3

What does the magic triangle look like?

Answer 3

Mass up top, Density bottom left Volume bottom right

Question 4

What are the units for mass?

Answer 4

Grams (g)

Question 5

What are the units for volume?

Answer 5

cm3 and mL

Question 6

Why does a substance sink or float in another?

Answer 6

If an object has a greater density than the liquid it is placed in, it will sink. If an object is less dense than the liquid it is placed in, it will float.

Question 7

What is the density of water? So, what is true about a water’s mass and volume?

Answer 7

1.00g/mL water’s mass and volume is a 1:1 ratio. Example: If water’s mass is 5g, its volume is 5mL

Question 8

How do you calculate density when you have mass and volume?

Answer 8

D=M/V

Question 9

How do you calculate volume when you have mass and density?

Answer 9

V=M/D

Question 10

How do you calculate mass when you have density and volume

Answer 10

M=DxV

Question 11

. What does it mean when someone says that density is a characteristic property of a substance?

Answer 11

Characteristic properties are not affected by the amount or shape of a substance. Density will always remain the same even when a substance’s mass/volume changes.
