SCIENCE BETCH Flashcards
All particles of matter are constantly moving in a random
manner and this is known as ______________________________
Brownian Motion
What is the movement of particles in a solid
(Name all 3)
- Held together by very strong forces of attraction
- Unable to move about freely
- Vibrate about in their fixed positions
What is the arrangement of particles in a solid
(Name all 2)
- Packed very closely together
- A fixed, regular pattern
What are the physical properties of a solid
(Hint: it is about shape, volume, density, and compression)
(Name all 5)
- Has a definite shape
- Have a definite volume
- Occupies the smallest volume
- Has a higher density than liquids
and gases - Cannot be compressed
What is the movement of particles in a liquid
( Name all 2)
- Held together by strong forces of attraction
- Able to slide past one another
What is the arrangement of particles in a liquid
(Name all 2)
- Packed closely together
- No fixed, regular pattern
What are the physical properties of a liquid
(Hint: Something about Volume, Shape, Density, compression.)
(Name all 5)
- Has no definite shape
- Has a fixed volume
- Occupies more volume than solids
- Has a lower density than solids
- Cannot be compressed
What is the movement of particles in a gas
- Held together by weak forces of attraction
- Able to move about freely over long distances
What is the arrangements of particles in a gas
- Far apart from one another
- No fixed, regular pattern
What are the physical properties in a gas
(Hint: Something about Volume, Shape, Density, compression.)
(Name all 5)
- Has no definite shape
- Have no definite volume
- Occupies the largest volume
- Has the lowest density
- Can be compressed
Why Does a Solid Have a Fixed Shape? (Name all)
The particles of a solid
* are held together by very strong forces of attraction;
* vibrate about fixed positions;
* cannot move about freely.
Why Does a Solid Have a Fixed Volume? (Name all)
A solid cannot be compressed because its particles are
already very close to one another.
Why Does a Liquid Not Have a Fixed Shape? (Name All)
The particles of a liquid:
* are arranged in a disorderly manner;
* have weaker forces of attraction;
* are not held in fixed positions;
* can move freely throughout the liquid.
Why Does a Liquid Have a Fixed Volume? (Name all)
The particles of a liquid are still packed quite closely
together.
Why Does a Gas Not Have a Fixed Shape? (Name all)
The particles of a gas:
* are spread far apart from one another;
* have the weakest forces of attraction;
* can move about rapidly in any direction.
Why Does a Gas Not Have a Fixed Volume?
Particles in gas are far apart from one another. There is
space for the particles to be compressed.
Gaining heat results in ________________
Expansion
Losing heat results in ________________
Contraction
What happens to the particle during contraction
1m if say : The particles move closer to one another.
1m if say : This causes the volume of matter to decrease.
1m if say : The particles lose energy and vibrate less vigorously.
What happens to the particles during expansion
1/2m if say: The particles move further.
1/2m if say: This cause the volume of matter to increase.
1m if say: This make the particles gain energy and vibrate more vigorously.
What occurs to the mass of matter during expansion and
contraction?
The mass of matter does not change during expansion and
contraction.
What occurs to the mass of matter during expansion and
contraction?
During expansion and contraction, the mass of a matter is
conserved.
What happens to the matter during melting and boiling
1m if say: the particles gain energy and vibrate more vigorously.
1m if say: they overcome the strong forces of attraction between one another. The particles break free from one another and move randomly.
What happens to the matter during freezing and condensation
1m if say: the particles lose
energy and move much
slower.
1m if say: they cannot overcome the forces of attraction between one another. The particles move closer to one another and move less randomly.
