1. Any sample of matter has mass and takes up space.
The main reason for this is because:
All matter is heavy
Matter can be a gas
Matter is made up of tiny particles that have mass and volume
The Earth is made of matter
What are two things you can say about water?
Water molecules are small
Water molecules are in motion
Water molecules are friendly and attracted to on another
Water molecules are wet
If you put food coloring in room temperature water, the coloring spreads throughout the water.
The water causes the color to spread mainly because:
Water molecules are warm
Water molecules are in motion
Water is more dense that food coloring
Food coloring molecules are small
Food coloring spreads out faster in hot water than in cold water because
Water molecules in hot water move more quickly
Molecules in hot water are larger
The food coloring molecules are small
Water is less dense than food coloring
When a thermometer is heated, the red liquid inside the thermometer moves up because
The red liquid is thin
Molecules of the liquid move faster and get a little further apart
Hot liquid is lighter
The glass of the thermometer gets hot
When you heat a sample of a solid, the sample gets a litter bigger because
The particles move faster and get a little further apart
Heat helps the particles grow
Heater the sample makes it lighter
Heater helps the particles slide past each other
Characteristics of a liquid include (choose ALL correct answers)
The particles of a liquid are attracted to one another
The particles of a liquid are in motion
The particles of a liquid are able to move past one another
A liquid has mass and takes up space
The characteristics of a sold include (choose ALL correct answers)
The particles of solid are attracted to each other
The particles of a solid can move past one another
The particles of a solid vibrate but do not move past one another
A solid has mass and takes up space
The characteristics of a gas include (choose ALL correct answers)
The particles are very attracted to each other
The particles are not very attracted to each other
The particles are close together like a liquid
The particles of a gas are further apart than the particles in a liquid or solid
In the process of conduction
Fast moving particles get larger
Slow moving particles get smaller
Fast moving particles transfer energy to slower moving particles
Slow moving particles transfer energy to faster moving particles
When water evaporates
Water molecules separate into one oxygen and two individual hydrogen atoms
The motion of water molecules causes them to stay in the liquid
The motion of water molecules cases them to leave the liquid and become a gas
The water increases in masss
When water vapor condenses
Water vapor changes from a liquid to a gas
One oxygen and two hydrogen atoms join to form a water molecule
Colder temperatures speed up the molecules
Water vapor is less dense than liquid water
Different liquids have different freezing points mainly because
Freezers are at different temperatures
Some winters are colder than others
The less liquid you use, the faster it freezes
Molecules of different liquids have a different amount of attraction
Dry ice turning from a solid to a gas is a process called
Condensation
Deposition
Evaporation
Sublimation
Turning a liquid to a gas is
Condensation
Deposition
Evaporation
Sublimation
Placing hot metal in cold water causes the temp of the metal to _________ and the temp of the water to _______
Decrease, Increase
Decrease, Stay the same
Stay the same, Decrease
Increase, Decrease
The density of an object is
Mass divided by volume D=m/v
Volume divided by mass D=v/m
The same as its weight
The same as the size of the object
If two objects have the same volume but one has more mass, the one with more mass
Has a lower density
Has a higher density
Will float
Will sink
If you cut a wooden block in half, each half would have
Half the density of the original piece
Twice the density of the original piece
The same density as the original piece
No density at all
If the density of water is 1 g/cm3 then the mass of 100 cm3 water would be
100 grams
50 grams
1000 grams
1 gram
The best way to find the mass of water in a graduated cylinder is
Take the total mass of the water and cylinder and subtract the mass of the water
Take the total mass of the water and cylinder and subtract the mass of the graduated cylinder
Add the mass of the water of the water to the mass of a cylinder
Take the total mass of the water and cylinder and divide the mass by two.
An object should float in a liquid if it is
More dense than the liquid
Less dense than the liquid
Lighter than metal
Shaped like a ball
A candle floats in water and sinks in rubbing alcohol because
The candle has less mass in alcohol
The water has less than the alcohol
The water is more dense than the alcohol
Water and alcohol are both liquids
The density of hot water
Is greater than the density of cold water
Is less than the density of cold water
The same as the density of cold water
Depends on the volume of water
How much stuff is stuffed in stuff
Mass
Volume
Density
Huh?
