Overall

Question 1

What is the word equation for density?

Answer 1

Density = Mass divided by Volume

Question 2

Units of measurement for mass

Answer 2

Milligrams/grams/kilograms

Question 3

Units of measurement for volume

Answer 3

Cubic centimetres, millilitres/litres

Question 4

Units of measurement for

Answer 4

g/cubic centimetre, g/millilitre

Question 5

While mass and volume are not characteristic properties of a substance, _________ is

Answer 5

density

Question 6

We can use the _________ of a substance to figure out what it is.

Answer 6

density (this is because when you have a substance, no matter how much of it you have, the density will always remain the same because the ratio of mass to volume stays the same)

Question 7

TRUE or FALSE- When you increase the temperature of a solid or a liquid, the particles start moving faster and going further away from each other

Answer 7

TRUE - the volume increases but the mass stays the same, causing the density to decrease

Question 8

TRUE or FALSE - When you heat a gas, the speeding up of the particles causes them to start colliding into each other less

Answer 8

FALSE - \when you heat a gas, the speeding up of the particles causes them to start colliding with each other more, which makes them come closer together. This means that the volume decreases but the mass stays the same, causing the density to increase

Question 9

TRUE or FALSE - The density of a substance is the measurement of how much mass is contained within a certain volume

Answer 9

TRUE

Question 10

TRUE or FALSE - When you increase the mass of a substance, but you leave the volume unchanged, the substance becomes more dense because there is now more mass within the same volume. The opposite happens when you decrease the mass of the substance

Answer 10

TRUE

Question 11

What happens when you increase the mass of a substance, but leave the volume unchanged?

Answer 11

The substance becomes denser because there is now more mass within the same volume.

Question 12

What happens when you drop and anchor into the ocean?

Answer 12

The water level drops when an iron anchor is dropped because it displaces less water with its volume than with its mass, unlike when it’s in the boat.

Question 13

What happens when you increase the volume of a substance, but you leave the mass unchanged?

Answer 13

The substance becomes less dense because the same amount of mass is now contained within a bigger volume
