Physical Properties
What property tells us how much matter is inside an object?
Mass
What are the three states of matter?
Solid, liquid, gas
What happens to puddles in the winter when it’s very cold outside?
They freeze and turn into ice.
What happens to ice when it gets warmer?
Melts
Name five solids you see in our classroom.
Desk, pencil, book, chair, notebook, etc.
What property describes how something feels, like rough or smooth?
Texture
Which state of matter has its own shape and its own volume?
Solid
You leave an ice cube on the counter, and it disappears. What is happening?
It melts into water.
What happens to water when it gets very cold?
It freezes
Name three examples of liquids.
Water, milk, juice
Name two properties you could use to describe a rock.
Color, size, shape, texture, hardness, mass, etc.
Which state of matter takes the shape of its container? Give an example.
Liquid (water, juice)
or
Gas (Oxygen, Water vapor)
Steam rises from a hot cup of tea. What change is taking place?
Evaporation – liquid is turning into gas.
A cold water bottle is taken outside on a hot day. Water droplets form on the outside. What process is happening, and where does the water come from?
Condensation; the water comes from water vapor in the air
Name two examples of gas.
Oxygen (O2) and Helium (He)
How would you find the mass of an object using a balance?
Place the object on the balance, adjust weights until level, and read the mass.
Water in a cup turns into water vapor on a hot day. What state change is happening?
Evaporation (liquid → gas)
You see drops of water on the bathroom mirror after a hot shower. What is this called?
Condensation
Evaporation and condensation are opposites.
Explain one way they are different.
Evaporation happens when a liquid warms and turns into a gas. Condensation happens when a gas cools and turns into a liquid
If I pour water from one cup to another of a different size, would its volume and shape remain the same?
The liquid would change shape but keep the same volume.
What is the difference between mass and volume? Give one example of each.
Mass = how much matter (rock weighs 200 g); Volume = space it takes (50 mL of water)
Ice cream melts on a hot day. What state of matter does it start as, and what does it become?
It starts as a solid and becomes a liquid.
Water in a pot starts bubbling and turning into steam on the stove. What is happening, and how is it different from evaporation?
Boiling – water is turning into gas quickly with bubbles, while evaporation happens slowly from the surface.
On a hot day, a puddle of water slowly disappears from the sidewalk. Explain what happens to the water and what process is taking place.
The water turns into water vapor and rises into the air. This process is called evaporation
Explain how freezing and melting help us in real life.
Freezing food, ice packs, melting ice for drinks, etc.
