Differences Between Mass
and WeightMass is . . .
• a measure of the amount ofmatter in an object.
• always constant for an object no matter where the object is in the universe.• measured with a balance• expressed in kilograms (kg),grams (g), and milligrams (mg).
Differences Between Mass
and WeightWeight is . . .
• a measure of the gravitational force on an object.
• varied depending on where the object is in relation to the Earth
(or any other large body in the universe).
• measured with a spring scale.
• expressed in newtons (N).
SolidSolid
Particles of a solid do not move fast enoughto overcome the strongattraction between them,so they are held tightly in place.The particles vibrate in place.
LiquidLiquid
Particles of a liquid move fast enough to overcome some of the attraction between them. The particles are able to slide past one another.
GasGasParticles of a gas move fast enough to overcome nearly all of the attraction between them. The particles move independently of one another.
GasGas Pressure Pressure
The balloon pops because the internal pressure is more than the balloon can hold
Examples of Chemical Changes
Soured milk smells bad because bacteria have formed new substances in the milk.
The hot gas formed when
hydrogen and oxygen join to
make water helps blast the
space shuttle into orbit.
Effervescent tablets bubblewhen the citric acid and bakingsoda in them react in water.
The Statue of Liberty is madeof shiny, orange-brown copper.But the metal’s interaction withcarbon dioxide and water hasformed a new substance, coppercarbonate, and made this landmarklady green over time.
