Concept explainers
(a)
Interpretation:
The term matter has to be defined.
Concept Introduction:
Matter: Anything that has mass and volume.
(a)
![Check Mark](/static/check-mark.png)
Explanation of Solution
Definition for Matter: Anything that has mass and volume (which means it takes up space) is considered as matter.
Even though matter appear to be smooth and continous it is actually composed of a lot of tiny little pieces called atoms and molecules.
(b)
Interpretation:
The term mass has to be defined.
Concept Introduction:
Mass: the amount of matter an object contains, it is measured in gram, kilogram.
(b)
![Check Mark](/static/check-mark.png)
Explanation of Solution
Definition for mass: The amount of matter (Anything that has mass and volume) in an object It is measure in gram, kilogram.
Mass of object is independed of its location.
(c)
Interpretation:
The term weight has to be defined.
Concept Introduction:
Weight: It is a force of gravity acting on an object.
Mass is the amount of matter an object contains.
(c)
![Check Mark](/static/check-mark.png)
Explanation of Solution
Definition for weight: It is a force of attraction between the object and the earth’s gravity. The weight of an object can vary from place to place and changes with its location on the earth.
(d)
Interpretation:
The term substance has to be defined.
Concept Introduction:
Substance: It is a kind of matter that cannot be separated into other kinds of matter by any physical or chemical changes.
(d)
![Check Mark](/static/check-mark.png)
Explanation of Solution
Definition for Substance: It is a kind of matter that cannot be separated into other kinds of matter by any physical or chemical changes.
A pure substance is composed of two or more elements whose composition is constant.
(e)
Interpretation:
The term mixture has to be defined.
Concept Introduction:
Mixture: Two or more pure substances that are mixed together but not joined chemically.
A pure substance is composed of two or more elements whose composition is constant.
(e)
![Check Mark](/static/check-mark.png)
Explanation of Solution
Definition for mixture: Two or more pure substances that are mixed together but not joined chemically. They are impure substances.
Example: salt water, smog.
