2: What is ductility
Ductility is a property of certain materials that describes their ability to be stretched or deformed without breaking.
Ductility is a property of certain materials that describes their ability to be crushed or smashed without breaking.
Ductility is a property of certain materials that describes their ability to be broken.
3: What is a physical property of matter
A physical property of matter is a characteristic that can be observed or measured without changing the substance's physical composition.
A physical property of matter is a characteristic that can be observed or measured by changing the substance's chemical composition.
A physical property of matter is a characteristic that can be observed or measured without changing the substance's chemical composition.
4: What is a chemical property of matter
A chemical property of matter describes how a substance behaves when it undergoes a chemical change or reaction
A chemical property of matter describes how a substance behaves when it undergoes a physical change
none of the above
5: What is a chemical property
A chemical property is a characteristic or behavior of a substance that describes how it can undergo physical changes to form new substances.
A chemical property is a characteristic or behavior of a substance that describes how it can undergo chemical reactions or changes to form new substances.
both of the above
6: What is a chemical change
A chemical change occurs when one or more substances are transformed into new substances with different chemical compositions.
A chemical change occurs when one or more substances are transformed into new substances with the same chemical compositions.
A chemical change occurs when one or more substances are transformed into new substances with different physical compositions.
A chemical change occurs when one or more substances are transformed into new substances with the same physical compositions.
7: What is state change
A state change, also known as a phase change, refers to the transition of elements from one state to another due to changes in temperature or pressure.
A state change, also known as a phase change, refers to the transition of matter from one state to another due to changes in temperature or pressure.
A state change, also known as a phase change, refers to the transition of matter from one state to another due to changes in density or viscosity
8: Why is a color change physical
A color change is often considered a physical property because it doesn't involve the alteration of the substance's chemical composition.
A color change is often considered a physical property because it involves the alteration of the substance's chemical composition.
A color change is often considered a physical chemical because it doesn't involve the alteration of the substance's chemical composition.
A color change is often considered a chemical property because it involves the alteration of the substance's chemical composition.
9: Why is matter that has a definite composition a homogeneous mixture
Matter with a definite composition is classified as a homogeneous mixture when its components are clumped together
Matter with a definite composition is classified as a heterogeneous mixture when its components are uniformly distributed throughout
Matter with a definite composition is classified as a homogeneous mixture when its components are uniformly distributed throughout
10: Why is a transparent liquid with a definite melting point either an element or a compound
A transparent liquid with a definite melting point is likely an element or a compound because their specific chemical structures allow for this property.
A transparent liquid with a definite melting point is likely an element or a compound because their specific physical structures allow for this property.

13: What is an element
An element is a substance made up of heterogeneous compounds
An element is a substance made up of solutions and mixtures.
An element is a substance made up of several types of atoms.
An element is a substance made up of just one type of atom.
14: What is a compound
A compound is when the same elements join together to make a new substance.
A compound is when different elements join together to make a new substance.
A compound is when different elements join together to make a mixture.

15: What is a solution
A solution is when one substance dissolves into another to make a mixture where everything reacts the same throughout.
A solution is when one substance dissolves into another to make a mixture where everything looks the same throughout.
A solution is when one substance dissolves into another to make a mixture where everything looks different throughout.
