Matter
a characteristic that you can observe
Property
Describe how the particles of a solid are packed
tightly together
Scientists use the ______ system for measurement
metric
a substance made of only one type of matter
element
How can you determine if one object has a greater density than another?
See if it floats more than the other object (buyancy) or divide the objects mass by its volume
kilograms or grams
A liquid has the same amount of _______ but takes the shape of the container.
volume
The amount of matter in a given space
density
All _____ in an element are alike.
atoms
Name a difference between mass and weight.
Mass is the amount of matter in an object, weight is the measurement of how strongly gravity pulls on the mass of that object.
Mass stays the same no matter where an object is, weight can change depending on gravity of planet
a tool that measures the amount of mass in an object
balance
The particles that make up a gas _____ the space around them.
fill
how do you find the area of an object if it is rectangular
multiply length by its width
What is the symbol for Gold?
Au
How can you chance the density of matter?
Add heat to the air (air particles move more quickly, spread out and rises above cooler, denser air)
Name an example of an unseen property of matter
magnetism, the ability of matter to dissolve in liquid
Name an example of each: solid, liquid, gas
varies
_____ describes the number of cubes that fit inside an object.
volume
Elements in the same column in a periodic table of elements have the similar _________.
properties
Describe the difference between the three states of matter.
metal - shiny, can be bent/hammered, let heat/electricity pass through them
metalloid - have some but not all properties of metal
non metals - no properties of metals. Gases.
a property of matter. It is an upward force of a liquid or gas on an object
buoyancy
Some objects can have multiple states. What are their names?
Non-Newtonian Fluids
to find volume you multiple the _____ by its ______ by its _______.
length x width x height
Which column contains the noble gases?
column 18
what is the purpose of the periodic table of elements?
- to classify the elements
- to use the patterns in the table to predict how an element will behave with other elements
