What are the 3 states of matter?
Solid, liquid, gas
What are the 2 types of pure substances?
Element and Compound
What are the two types of mixtures?
Homogeneous and Heterogeneous
Density is the ability for an object to...
Sink or Float
Any object with low density will...
Float
Which state of matter has a DEFINITE shape
solid
Where can you find elements
The periodic table of elements
True or False: Homogeneous mixtures have a uniform look to them as you cannot see the separation between the particles
True
Tom through a ball and it sunk. What does this say about its density compared to water?
It is more dense than water
Name a famous scientist
Marie Curie, Albert Einstein, Issac Newton, Jane Goodall, Neil DeGrasse Tyson
Describe the kinetic energy of each state of matter.
Solids have very low kinetic energy
Liquids have more kinetic energy than solids but less than gasses
Gasses have the most kinetic energy of all the states
an element is made of
a. one type of atom
b. more than one type of atom
A. one type of atom
30 seconds to name 5 homogeneous mixtures
salt water, peanut butter, chocolate, sugar water, kool aid
Water has a density of 1.83. Honey has a density of 1.80. Is honey going to sink or float in water?
Float because it has less density.
What is the type of science that studies weather?
Meteorologist
You have 30 seconds to determine whether each state of matter has definite or indefinite volume
solids and liquids = definite
gasses =indefinite
Is water a compound or element
compound
30 seconds to name 5 heterogenous examples
salad, rocks in water, sandwich, fruit in yogurt, hot cocoa and marshmallows
If something has small volume but big mass it will be
a. more dense
b. less dense
a. more dense
Which one is the real science Astronomy or Astrology
Astronomy
How does the kinetic energy of an object affect its shape?
The more kinetic energy an object has the less definite of a shape. The less it has the more definite the shape.
Is hydrogen a liquid, solid or gas
gas
is ice in water heterogeneous or homogeneous
Heterogeneous
If something has a big volume but small mass would it be more dense or less dense?
Less because when something takes a lot of space but doesn't weigh a lot the volume to mass ratio would say less dense
Name a constellation
big dipper, little dipper, hercules, orions belt etc
