Properties of Liquids

In this worksheet, students will consider the properties of familiar liquids using descriptive vocabulary and the scientific words used to describe changes of state from liquid to gas and solid to liquid.

Worksheet Overview

QUESTION 1 of 10

Think about the different liquids in your home. They have many different properties.

 

Liquids can be colourless, or coloured:

Goldfish in bowl Orange juice pouring

 

Odourless or smelly:

Pefume sprayer

 

Transparent or opaque:
 

Spilled paint

 

And very runny or really gloopy:

Honey on spoom

 

Let's find out about the properties of liquids.

Which THREE of these are liquids at room temperature?

ice

petrol

set jelly

pancake batter

golden syrup

Which TWO 'property' words best describe water?

soft

odourless

blue

colourless

cold

We make new liquids by dissolving solids in water (the solvent).

 

When solids dissolve, they form a clear liquid. Which THREE of these solids dissolve in water? 

salt

sugar

sand

black pepper

coffee granules

Khadija and Omar make a salt solution by mixing salt with water. They pour some into a petri dish and leave it on the window sill above a radiator.

 

After a few days, what solid is left in the dish?  Type your answer into the box.

Omar and Khadija need to explain, using science vocabulary, what has happened to the water. They know the water from the dish is now in the air around them.

 

Can you help them by choosing the word that explains this change?

condensation

conduction

evaporation

escaping

Melting is a reversible change. Some solids, when heated change into liquids.

 

Which THREE solids in this list melt into liquid?  

gold

margarine

cement

wax

wood

Gases can change into liquid in a process called condensing.  What must happen to bring about this change?

kept the same temperature

cooled down

heated up

Identify the THREE examples of condensing in these changes.

batter to yorkshire puddings

using an aerosol deoderant

formation of clouds

water droplets on the outside of a cold drink

water vapour when we breathe onto a mirror

Khadija has noticed that some liquids flow more easily than others. This measure of 'gloopiness' has a special name.

 

Do you know what is this property called?

stickiness

flow

viscosity

hardness

  • Question 1

Which THREE of these are liquids at room temperature?

CORRECT ANSWER
petrol
pancake batter
golden syrup
EDDIE SAYS
Ice is water in its solid form. Pancakes are soild, but the batter used to make them is a thick liquid. (No lumps please!)
  • Question 2

Which TWO 'property' words best describe water?

CORRECT ANSWER
odourless
colourless
EDDIE SAYS
Colourless is the proper scientific word for 'clear' - it means that something has no colour. Similarly, odourless means it has no smell (odour). Oceans may look blue, but that's because of the way light is reflected back off it and what's under the water; for example, having blue coloured tiles in a swimming pool.
  • Question 3

We make new liquids by dissolving solids in water (the solvent).

 

When solids dissolve, they form a clear liquid. Which THREE of these solids dissolve in water? 

CORRECT ANSWER
salt
sugar
coffee granules
EDDIE SAYS
Be careful! Don't confuse clear with colourless! Here 'clear' means that there are no bits floating around - in other words, the solid dissolves completely . In the case of coffee, the granules are brown and dissolve completely to make a clear brown solution. Make sense?
  • Question 4

Khadija and Omar make a salt solution by mixing salt with water. They pour some into a petri dish and leave it on the window sill above a radiator.

 

After a few days, what solid is left in the dish?  Type your answer into the box.

CORRECT ANSWER
salt
white crystals
EDDIE SAYS
The salt and water mixture can be separated because dissolving is a reversible change. So crystals of salt would remain once the water has evaporated away.
  • Question 5

Omar and Khadija need to explain, using science vocabulary, what has happened to the water. They know the water from the dish is now in the air around them.

 

Can you help them by choosing the word that explains this change?

CORRECT ANSWER
evaporation
EDDIE SAYS
When liquid turns to a gas, we say it has evaporated. Condensation is the exact opposite - that's when a gas (like water vapour) touches a cold surface and cools down into a liquid (like on the outside of your iced fizzy drink on a hot day).
  • Question 6

Melting is a reversible change. Some solids, when heated change into liquids.

 

Which THREE solids in this list melt into liquid?  

CORRECT ANSWER
gold
margarine
wax
EDDIE SAYS
Metals become liquid at high temperatures. Wax, like in candles, needs to be heated gently in order to melt it. Cement is a thick liquid but it hardens because of a chemical non-reversible change. It cannot be changed back into a liquid by heating. Wood is made of material that doesn't melt - it only burns.
  • Question 7

Gases can change into liquid in a process called condensing.  What must happen to bring about this change?

CORRECT ANSWER
cooled down
EDDIE SAYS
When a gas condenses, it means that it's been cooled down sufficiently to turn from a gas into a liquid. You've seen condensation on your bathroom mirror - that's warm steam touching the cold mirror and condensing into water droplets.
  • Question 8

Identify the THREE examples of condensing in these changes.

CORRECT ANSWER
formation of clouds
water droplets on the outside of a cold drink
water vapour when we breathe onto a mirror
EDDIE SAYS
Condensing water forms small droplets which we can see. The moisture which forms on the outside of cold drinks condenses from the air around the can or glass. In an aerosol can the opposite is happening - liquid is under pressure inside the can; when you press the nozzle, it releases some of that pressure and the liquid sprays out as little droplets and gas.
  • Question 9

Khadija has noticed that some liquids flow more easily than others. This measure of 'gloopiness' has a special name.

 

Do you know what is this property called?

CORRECT ANSWER
viscosity
EDDIE SAYS
Now that's a tough word! When a liquid (like syrup) is thick, scientists describe it as VISCOUS. Liquids which flow easily have a low viscosity, for example, water. Liquids which flow slowly, like runny honey, have a high viscosity. New word? Worth remembering that one!
