Why will food coloring move throughout water without being stirred?
Water molecules are in motion.
The food coloring is smaller than water.
The food coloring contains energy.
The water molecules are larger.
Food coloring will move faster throughout warm water than in cold water because...
The water molecules in cold water move faster.
The water molecules in warm water move faster.
The water molecules in cold water don't move.
The food coloring is the only molecules that move.
Which statement is NOT true of solids?
The particles of a solid are attracted to each other
The particles of a solid vibrate in place.
A solid has mass and takes up space.
The particles of a solid move around each other.
When water evaporates...
Water molecules break into oxygen and hydrogen.
The motion of the molecules cause them to stay as a liquid.
The water increases in mass.
The motion of the molecules cause them to leave the liquid as gas.
When water vapor condenses... (chose all that apply)
Water vapor changes from a gas to a liquid.
energy decreases
molecules become more attracted to each other
Liquid water changes to a gas
In a thermometer, the red liquid moves up because...
The red liquid is thin.
The molecules move faster and further apart.
The molecules move slower and closer together.
The glass of the thermometer gets hot.
When you heat a substance...
the molecules move slower
the molecules move faster
the molecules stop moving
the molecules get closer together
Chose all that apply. Which statements describe a liquid?
particles are attracted to each other more than a gas.
particles are able to move past each other
participles are in motion
particles do not move
Ice melts to liquid mainly because...
The water molecules move fast enough to break down their fixed positions.
Water molecules slow down so much they melt.
Ice is more dense than water.
Water molecules react with oxygen to produce melting.
To determine the density of an object...
divide volume by mass D= V/M
divide mass by volume D = M/V
