What is Matter?
Matter is anything that has mass and occupies space.
What is density?
What is how tightly matter is packed within a given volume—the amount of space an object occupies.
What is a compound?
What is a substance formed when two or more different chemical elements are chemically bonded together.
What is a physical change?
What is a change that affects one or more physical properties of a substance.
How is density used in real life?
What is density helps in determining whether objects will float or sink in a fluid.
What are the three states of matter?
Solid, liquid, and gas
What is a chemical property?
What is the ability of a substance to undergo a chemical change or reaction that results in a change in the substance's chemical identity.
What is a mixture?
What is a combination of two or more substances that are physically combined but not chemically bonded.
What is a chemical change?
What is a process where one or more substances are transformed into entirely different substances with new chemical properties.
Why is the Law of Conservation of Mass important?
What is it is crucial for understanding chemical reactions and balancing equations in chemistry.
What is a pure substance.
What is matter with a uniform and definite composition, consisting of only one type of atom or molecule.
Give an example of a physical property listed in Ms. Gresham's Google Slide Show.
What is color, density, hardness, melting point, and boiling point.
What is a homogeneous mixture?
What is a mixture consisting of parts all of the same kind.
Give an example of physical change and chemical change from Ms. Gresham's Google Slide Show.
Physical change: melting ice
Chemical change: wood turning into ashes.
What is an example of a chemical property used in an industry.
What is reactivity of sodium in chemical manufacturing.
What is a heterogeneous mixture?
What is a substance or mixture where the components are not evenly distributed and have distinguishable parts.
What is a chemical change?
What is a process where one or more substances are transformed into entirely different substances with new chemical properties.
What is an element?
What is a basic part of a whole, with its basic part being an atom that contains protons, neutrons, and electrons.
How can you tell if a chemical change has occurred?
What is color change, gas production, temperature change, or precipitate formation.
How do mixtures affect food production?
What is for creating consistent flavors and textures in food products.
What is a physical change?
What is a change in the form or appearance of a substance, such as a change in size, shape, or state.
Explain the Law of Conservation of Mass & Energy.
What is a law that states that mass can be transformed into energy and energy can be transformed into mass, but the overall sum of mass and energy remains the same.
What makes a pure substance unique?
What is a pure substance has a uniform and definite composition, consisting of only one type of atom or molecule.
What is the difference between physical and chemical properties?
What is physical properties can be observed without changing the substance, while chemical properties describe how a substance reacts to form new substances.
Describe how understanding states of matter is important in science.
What is it helps in explaining things such as evaporation, condensation, and the behavior of gases.
