Unit 5 C2 Density

Question 1

How do we define density?

Answer 1

The density of a material is defined as the mass per unit volume of the material.

Question 2

What are the standard units for density?

Answer 2

Question 3

What is the equation to calculate density?

Answer 3

Question 4

What do each of the letters stand for in the equation for calculating density?

Answer 4

P = Density
M = Mass
V = Volume

Question 5

Give a method for measuring the density of a regular solid.

Answer 5

Measure the mass of the object using a balance​.

Calculate volume of the object by measuring with a ruler, then using the relevant calculation.​

Do the density calculation

Question 6

Give a method for measuring the density of an irregular solid.

Answer 6

Measure the mass using a balance​.

Read off the volume from a beaker or measuring cylinder without and then with the object submerged in the water​.

The difference in volumes is the volume of the solid​.

Do the density calculation.

Question 7

Give a method for measuring the density of a liquid.

Answer 7

Measure mass of a container using a balance, then the mass of the liquid and the container together​

The difference between the two measurements is the mass of the liquid​

Read off the volume from a beaker or measuring cylinder​

Do the density calculation
