Which statement BEST summarizes that particulate theory of matter?
All matter are made of tiny particles that are in constant motion, have force of attraction between them, and occupies space.
All matter have tiny particles that are in constant motion when heat is applied, and will exhibit buoyancy when it occupies space.
All matter is has mass and occupies space hence matter change increases with kinetic energy.
All matter have particles, motion, force, and space.
The force of attraction between particles of a solid can be described as:
Strong
Weak
Vibrant
Moderate
The Kinetic theory can be used to explain how solids, liquids, and gases differ in _____________ and ___________.
movement and arrangement
space and weight
movement and weight
energy and temperature
A substance has a boiling point of 90°C. What changes occur when it is heated from 50°C to 120°C?
energy of particles increase; attractive forces decrease
energy of particles decrease; attractive forces increase
energy of particles increase; attractive forces increase
energy of particles decrease; attractive forces decrease
The three states of matter are represented by diagrams X, Y and Z. Which change occurs during condensation?
X to Y
X to Z
Y to X
Z to X
Thermal energy is...
heat energy
the energy of motion
energy of nuclear processes.
an indication of physical change.
Which state of matter has particles that are somewhat close together and have enouch kinetic energy to slide past each other?
solid
liquid
gas
The force of attraction between particles of a solid can be described as:
Strong
Weak
Vibrant
Moderate
Which statement about liquids is correct?
They have a fixed shape and a fixed volume.
They have a fixed shape but not a fixed volume.
They have no fixed shape but they do have a fixed volume.
They have no fixed shape and no fixed volume.
The particles of solids ________________
vibrate about their fixed postions
are able to slide over each other
move about freely at high speeds and in random direction
do not move
The particles of gases ________________
vibrate about their fixed postions
are able to slide over each other
move about freely at high speeds and in random direction
do not move
Arrange the strength of the forces of attraction between the particles of solids, liquids and gases from the strongest to weakest
(strongest) gases > liquids > solids (weakest)
(strongest) solids > liquids > gases (weakest)
(strongest) gases > solids > liquids (weakest)
(strongest) solids > gases > liquids (weakest)
What happens to particles of liquid when they are heated?
They slide over one another faster and move further apart
They slow down and compress
They stop moving
They slide over one another slower and move closer together
Why does solid has a fixed shape?
The particles are held by very strong forces of attraction. They can only vibrate about their fixed position. Hence, they have an orderly arrangement.
The particles are held by weak forces of attraction. They can move rapidly in all directions. Hence, they have an disorderly arrangement.
The particles are held by strong forces of attraction. They can slide over one another. Hence, they have an disorderly arrangement.
