What is Matter?
What is Matter?
What is anything that has mass and takes up space?
What are the three main states of matter?
What is Solid, Liquid, Gas?
What is melting?
What is a solid changes into a liquid?
What does soluble mean?
What is a substance that can dissolve in another substance.
What is a physical change?
What is a change that does not create a new substance?
Is air matter even though we cannot see it? Why?
What is Yes! Air has mass and takes up space.
Which state of matter has a definite shape and volume?
What is solid?
What is freezing?
What is a liquid changes into a solid?
What does insoluble mean?
What is a substance that does not dissolve in another substance?
What is a chemical change?
What is a change that creates one or more new substances?
What are the tiny particles that make up matter called?
What is atoms?
How are particles arranged in a solid compared to a gas?
What is solid particles are tightly packed; gas particles are spread far apart?
What is evaporation?
What is a liquid changes into a gas?
Name three physical properties of matter.
What is color, texture, hardness, magnetism, reflectivity, density, or buoyancy?
Name two signs that a chemical reaction has occurred.
What is gas bubbles, color change, temperature change, light, or formation of a new solid?
What is a compound?
What is a substance made of two or more different elements chemically combined?
Which state of matter takes the shape of its container but keeps the same volume?
What is condensation?
What is how much matter is packed into a certain amount of space?
What is the Law of Conservation of Matter?
What is matter cannot be created or destroyed, only transformed?
How can atoms combine to make different compounds?
What is atoms join together in different combinations to form compounds?
Explain how particles move differently in solids, liquids, and gases.
What is solid particles vibrate in place, liquid particles slide past one another, and gas particles move freely and spread apart?
What happens to the particles of matter when thermal energy is added or removed?
What is adding thermal energy makes particles move faster; removing thermal energy makes them move slower?
How could you use physical and chemical properties to identify an unknown white powder?
Test solubility, magnetism, and reactions with other substances, then compare results with known powders?
If two substances react and form a new substance, does the total amount of matter change? Explain.
What is no, the total amount of matter stays the same, even when new substances form?
