The heavier a particle, the ___ it moves.
slower
What determines the speed of the atoms and molecules of a particular substance?
Both (a) and (b)
Archimedes' principle states that the buoyant force on a(n) ___ is equal to the weight of the displaced volume of fluid.
object in the fluid
The resistance of a fluid to flow is referred to as
viscosity.
Which state of matter will hold its shape without a container?
solid
The kinetic theory states that the higher the temperature, the faster the
particles that make up a substance move.
Evaporation refers to the change of state from a
liquid to a gas.
The law of conservation of mass states that mass cannot be
created or destroyed.
Ice floats in water because it is
less dense than water.
Buoyant force is the ___ force exerted on an object immersed or floating on a liquid.
upward
The engine of a car left running for a long period of time becomes hot because
energy is transferred from burning gasoline.
A substance changes from a liquid to a gas during evaporation because
energy is absorbed.
What happens to the particles of a substance that condenses?
Particles slow down and clump together.
The notion that an object floats if the buoyant force on the object is equal to the object's weight was described by
Archimedes.
The ability to an object to float on a fluid is influenced by the
All of the above
The speed at which fluid flows through a pipe is influenced by the
All of the above
As the pressure of a moving liquid increases, its speed
decreases.
Bernoulli's principle describes the property of a(n)
fluid in motion.
Upward force exerted on an object immersed or floating on a liquid is called
buoyant force.
Which of these properties is shared by solids, liquids, and gases?
Their particles are in constant motion.
A measure of the average kinetic energy of the particles in an object is called
temperature.
The process of a liquid becoming a solid is called
freezing.
A state of matter that is not a fluid is
solid.
Which state of matter has a definite volume, but not a definite shape?
liquid
The kinetic theory helps to explain the differences between
states of matter.
A solid becomes a gas through a process called
sublimation.
A gas becomes a liquid through a process called
condensation.
The force keeping an object floating on a liquid is called
buoyant force.
Pascal's principle states that a fluid in equilibrium enclosed by a vessel exerts pressure
equally in all directions.
How does the density of an object floating on a fluid compare to the density of the fluid?
The floating object is less dense.
Unlike a plasma, a gas
does not conduct electricity.
