Unit 1 mongus Flashcards
Observation
Any use of the five senses
mass
amount of matter (solids,liquids,gas) in an object
weight
measure of gravity pull in mass (grams)
volume
amount of space occupied by an object (cm3)
vol of cube
l x w x h
Inference
A guess based on an observation
vol of odd shape
vol of odd shape
water displacement
desnity of e
density
concenentration of matter in an object
how to do density
Density equation
m/v
denisty
density unit of measurement
g/cm3
how does densigty chnage
how does density change?
done by temperature increase if decrease
temperature increase
atoms speed up and expand, volume increases, density decreases
tepsature decrease
temature decrease
atoms slow down and go togetehr, volune decrease, density increase
pressurfe ibcreade
pressure increase
atoms compact, volume decrease, density increase,
pressure decrease
atoms expand, density decrease.
direct graph
when graph goes up diagonal
indeirevt
indircet
when graph goes down diagonal
cycle graph
loopty loop
constant
straight line
atmosphere
thin shell of gases surrounding earth
what is the atmosphere made up of
78 percent nitrogen 21 percent oxygen and other tricky 1 percent
lithosphere
thin lair of the earth that makes up the Earth’s surface
hydrosphere
thin layer of water resting on the crust
where is less dense
in the atmosphere
When pieces go up
Density stays the same (constant)
When Volume goes up
Mass goes up (direct)
When volume goes up
Pressure goes down (indirect)
When volume goes up
Temperature goes up (Direct)
When Density goes up
Temperature goes down (indirect)
When Density goes up
Pressure goes up (Direct)
