Solids
I have a definite shape and a definite volume. Which state of matter am I?
What is a solid?
I have a definite volume but no definite shape. I take the shape of my container. Which state of matter am I?
What is a liquid?
I have no definite shape and no definite volume. I spread out to fill any container. Which state of matter am I?
What is a gas?
A substance made of only one type of particle throughout is called what?
What is a pure substance?
Which state of matter—solid, liquid, or gas—has particles with the least kinetic energy?
What is a solid?
In a solid, the atoms and molecules are packed tightly together and vibrate in place. What do we call this movement of particles?
What is kinetic energy?
The particles in a liquid are farther apart than in a solid. This allows liquids to do something solids cannot do. What is it?
What is flow?
Gas particles have the most kinetic energy of all three states of matter. What does this mean about how fast they are moving?
What is they are moving very fast?
Salt water is an example of what type of mixture where you cannot see the different parts?
What is a homogeneous mixture or solution?
If you mix sand and water, can you easily separate them by filtering? What type of mixture is this?
What is a heterogeneous mixture?
A block of ice keeps its shape whether you put it in a cup or a bowl. What property of solids does this demonstrate?
What is the definite shape?
When you pour milk from a pitcher into a glass, the milk changes shape but not volume. What property of liquids does this show?
What is definite volume but no definite shape?
When you open a bottle of perfume in a room, the smell spreads throughout the entire room. What property of gases does this demonstrate?
What gases spread out to fill available space?
In a heterogeneous mixture, you can see the different parts mixed together. Which is a better example: salt water or trail mix?
What is trail mix?
When you dissolve sugar in water, the sugar disappears and looks like one substance. What type of mixture is this?
What is a homogeneous mixture or solution?
When you heat a solid, its atoms and molecules move faster and vibrate more. What happens to the kinetic energy of the particles?
What is it increasing?
Compared to a solid, do the particles in a liquid have more or less kinetic energy?
What is more kinetic energy?
The particles in a gas are very far apart compared to solids and liquids. How does this affect the volume a gas takes up?
What gas expands to fill the entire volume of its container?
A solution is a special type of homogeneous mixture. In salt water, what is the substance that dissolves called?
What is the solute?
Rank solids, liquids, and gases from lowest to highest kinetic energy of their particles.
What is solid, liquid, gas?
Explain why a wooden table does not flow or change shape like water does, using what you know about particle arrangement.
What if the particles in a solid are tightly packed and held in fixed positions, so they cannot move around freely?
Why can you stir a cup of juice but you cannot stir a block of cheese, even though both are matter?
What if the particles in a liquid can move around and slide past each other, while particles in a solid are fixed in place?
Explain why a balloon filled with helium gas takes up space, even though you cannot see the gas inside it.
What if the gas particles are moving rapidly and spreading out in all directions to fill the balloon, even though the particles are invisible to our eyes?
Compare a glass of pure water to a glass of salt water. Explain why one is a pure substance and the other is a mixture.
What is pure water containing only water molecules, making it a pure substance, while salt water contains both water molecules and salt particles mixed together, making it a mixture?
Explain why you can see the different parts in a bowl of cereal and milk but you cannot see the different parts in a glass of lemonade, using what you know about mixtures.
What is cereal and milk is a heterogeneous mixture where you can see the separate parts, while lemonade is a homogeneous mixture where the sugar and flavoring are completely dissolved and mixed throughout, so you cannot see the separate parts?
