Density

Question 1

Density

Answer 1

Density Describes how tightly matter is compacted together in a substance

Question 2

Volume

Answer 2

How much space a substance takes up

Question 3

Mass

Answer 3

The amount of matter in a substance

Question 4

Density Formula

Answer 4

Mass divided by volume

Question 5

Mass Formula

Answer 5

Density x Volume

Question 6

Volume Formula

Answer 6

Mass divided by density

Question 7

What makes something more dense

Answer 7

Tightly closer packed particles are denser as there are more particles

Question 8

What decreases density

Answer 8

Heating particles (causing them to spread out) decreases density

Question 9

When does density increase

Answer 9

Density increa

ses as the particles become more tightly packed

Question 10

Why do solids have the highest density

Answer 10

Solids have the highest densities as their particles are closely packed

Question 11

How to calculate volume

Answer 11

Length times width times breadth

Question 12

How to calculate density of a liquid

Answer 12

• Use balance to measure the mass of an empty graduated cylinder
• Add the liquid into the graduated cylinder and then calculate the mass using a balance.
• The difference between both masses is the mass of the liquid itself
• Record the volume of the liquid
• Use density formula to calculate formula

Question 13

Archimedes Principle

Answer 13

If you place an object in water the volume of the water displaced out of the container is equal to the volume of the object

Question 14

What does the density of a material determine?

Answer 14

The density of a material determines whether it will float or not

Question 15

How will an object float

Answer 15

An object floats if it is less dense than the liquid it is put in

Question 16

How will an object sink

Answer 16

An object will sink if it is denser than the liquid it is put in

Question 17

What will a less dense liquid do?

Answer 17

A less dense liquid will will float on a liquid with higher density

Question 18

To float

Answer 18

|To mover or hiver slowly and lightly in air or on the surface of a liquid

Question 19

Why does Ice float

Answer 19

As water freezes its particles spread out and form ice. Ice can float on water as its particles are not compact thus making it less dense

Question 20

Flotation

Answer 20

A solid will float if it has a lower density that the liquid it is placed in
A liquid will float on top of another liquid if it has a lower density than that liquid

Question 21

How to Calculate Density

Answer 21

• First calculate the mass using a mass balance

- Calculate the volume using the volume formula. Length by Width by Height

Question 22

How to Calculate the Density of an Irregular object

Answer 22

• Mass: Use a balance to calculate the mass of the irregular object
• Completely fill an overflow can with water
• Place the irregular object inside the can
• Collect the displaced water in a graduated cylinder. The amount of water in the graduated cylinder is equivalent to the misplaced water and also the volume of the irregular object

Question 22

How to Calculate the Density of an Irregular object

Answer 22

• Mass: Use a balance to calculate the mass of the irregular object
• Completely fill an overflow can with water
• Place the irregular object inside the can
• Collect the displaced water in a graduated cylinder. The amount of water in the graduated cylinder is equivalent to the misplaced water and also the volume of the irregular object
