The Particle Theory Flashcards
1
Q
What is Matter?
A
Matter is anything having & mass and taking up space
2
Q
What are the five particle rules?
A
- all matter is made up of tiny particles
- different substances are made up of different particles
- particles are in constant motion
- the particles in a substance move faster as its temp increases
- particles attract each other
3
Q
What are the properties of a solid state?
A
- particles close together in a pattern
- strong attractive forces. between particles
- particles can vibrate in a fixed position
4
Q
What are the properties of a liquid state?
A
- particles are fairly close together in groups
- weather attractive forces between particles
- particles move around or slide past one another
5
Q
What are the properties of gas state?
A
- Particles far apart
- very weak attractive forces
- particles move apart
6
Q
Which state is the most dense?
A
Solid
7
Q
Which state has a definite volume?
A
solid, liquid
8
Q
Which state is the least dense?
A
Gas
9
Q
Which element is an exception to these rules and why?
A
Water because the solid state (ice) is less dense than the liquid state. water expands as it freezes
10
Q
Temperature is a measure of what?
A
Kinetic energy
11
Q
matter in exists in three states
A
solid,liquid,gas
12
Q
the physical state of a substance depends on?
A
temperature and pressure
13
Q
A change of state is a?
A
physical change
14
Q
a chemical change is when?
A
a new substance is created
