Basic Chemistry Flashcards
Is anything that occupies a space and has mass.
Matter
Refers to the quantity of matter in any body.
Mass
Refers to the gravitational attraction exerted by a large body of matter on an object.
Weight
_____ is dependent on gravity, therefore, it depends upon the distance of the body from the center of the Earth and so may vary from place to place.
Weight
Properties like Odor, color, taste transparency, and physical state.
Physical Properties
Are determined by our senses and therefore they are not always reliable.
Physical Properties
Are density, boiling point and freezing point are physical properties that are reliable because they can be measured and numerical values are assigned to them. True or False
True
Those properties that can be observed only when the substance undergoes a change in composition. These are also the properties that determine the ability of a substance to react with other substances.
Chemical Properties
What are the Physical States of Matter
Gases, Liquids, Solids and Plasma
Are substances that neither have definite shape nor definite volume.
Gases
Are substances that have definite volume but no definite shape. They just follow the shape of the container.
Liquids
Are materials that have definite volume and definite shape.
Solids
Is a mixture of sub-atomic particles nuclei and electrons.
Plasma
Basic building blocks of matter is called______.
Atom
Is the tiny central part of an atom that contains the protons and the neutrons.
Nucleus
