volume
amount of space occupied by an object
mass
the amt of matter that something is made up of
weight
a measure of the gravitational force of an object
physical property
can be observed or measured w. out changing the identity of the matter
density
amount of matter in a given space or volume (or mass per unit volume)
matter
anything that has volume or mass
Inertia
tendency of objects to resist any change in motion
meniscus
the curve you see @ a liquids surface
gravity
the force of attraction between objects due to their masses
SYMBOL FOR mass
m
symbol for volume
V
formula for density
D=m/v
what is density an example of?
physical property
what remains constant during a phase change?
temperature
states of matter
the physical forms in which substances can exist
what are the 4 states of matter?
solid, liquid, gas, & plasma
solid
state in which matter has a definite shape and volume
liquid
state in which matter takes the shape of its container and has a definite volume
gas
state in which matter changes in both shape & volume
pressure
amount of force exerted on a given area
plasma
state of matter that doesnt have a definite shape or volume and whose particles have broken apart
crystalline
orderly arrangement of atoms
amorphous
atoms in no particular order
formula for average speed
v=d/t
on earth, what is the rate of objects accelerating towards earth?
9.8 m/s/s
how much does a falling object increase its speed every second?
9.8 m/s
what does not affect the rate of acceleration?
mass of an object
formula for work
W=Fd
the unit for work
joules
What is mass measured with?
a balance
What is mass expressed in?
kg, g, mg
how to measure or determine liquid volume
measured in liters (L) and milliliters (mL) by looking at the bottom of the meniscus
what is solid volume expressed in?
expressed in cubic meters(m^3) & cubic cm(cm^3)
unit for solid volume
V=length*width*height
how is weight measured and what is it measured in?
spring scale, newtons(N)
compare volume & mass
anything w/ volume or mass is matter
compare mass & weight
mass= matter in object
weight= grav force of object
relationship between mass and inertia
amount of mass affects amount of inertia
how do mass & dist. affect force of gravity between objects?
smaller mass and longer dist= smaller force of gravity between
What are the 5 changes of state?
freezing, melting, vaporization, condensation, sublimation
difference between exothermic change and endothermic change
exo= realease energy
endo= takes in energy
Fr
francium
Ra
radium
Eu
europium
Pu
plutonium
solid
state in which matter has definite shape and volume
liquid
state in which matter takes shape of its containerand has definite volume
gas
state in which matter changes in both shape & volume
Boyle's Law
for a fixed amt of gas at a constant temp, volume of a gas increases as its pressure decreases
Charle's Law
for a fixed amt of gas @ a constant pressure, volume of gas increases as its temp increases
plasma
doesnt have definite shape or volume and particles broken apart
Melting
soliod to liquid, endothermic
freezing
liquid to solid, exothermic
vaporization
liquid to gas, endothermic
compare boiling & avaporation
boiling occurs throught liquid, evap occurs on surface of liquid
sublimation
solid to gas, endothermic
