Properties of Matter
What is matter?
Matter is anything that has mass and takes up space.
What is a solid?
A solid has a fixed shape and volume with tightly packed particles.
What are atoms?
Atoms are the smallest units of matter that retain chemical properties.
What are the parts of an atom?
Protons, neutrons, and electrons.
How does understanding matter help in technology?
It helps in developing materials with specific properties for various applications.
List 3 examples of matter around us.
Examples include desks, water, and air.
Describe a liquid.
A liquid has a fixed volume but takes the shape of its container.
Define molecules
Molecules are two or more atoms bonded together.
What is the charge of a proton?
Protons have a positive charge.
Name a scientific field that studies matter.
Chemistry.
What is the difference between matter and non-matter?
Matter has mass and takes up space, while non-matter (like light or energy) does not.
What is a gas?
A gas has no fixed shape or volume and fills its container.
What is a tissue?
A tissue is a group of similar cells that work together to perform a function.
Name the three subatomic particles.
Protons, neutrons, and electrons.
How does matter play a role in chemical reactions?
Matter undergoes changes in composition and properties during chemical reactions.
Can you think of something that is not matter?
Light, energy, and thoughts are not matter.
Explain melting and freezing.
Melting is the change from solid to liquid, while freezing is from liquid to solid.
Explain the hierarchy from atoms to organisms.
Atoms form molecules, which form cells, tissues, organs, organ systems, and finally organisms.
Why are atoms called the building blocks of matter?
Atoms combine to form all matter, making them fundamental units.
Explain how density affects material selection in science.
Density helps determine material suitability based on weight and space constraints in experiments.
Why is mass important in measuring matter?
Mass determines how much matter is present and affects weight and density.
What happens to particles during vaporization?
Particles gain energy and move apart, transitioning from liquid to gas.
What is an ecosystem?
An ecosystem is a community of living organisms interacting with their environment.
How do atoms combine to form molecules?
Atoms bond through chemical reactions.
How is matter studied in environmental science?
Matter is studied to understand pollution, resource management, and ecosystem interactions.
