States of Matter
What are the 4 states of matter?
Solid, Liquid, Gas, Plasma
What holds particles together?
What is the boiling point of water in celcius?
100 degrees C
What is kinetic energy?
Particles in motion
What is the difference between plasma and all other states of matter?
Particles that move freely are:
Gas particles
What is the freezing temperature of water in Fahrenheit?
32 degrees Fahrenheit
How do molecules move in gas?
Quickly and spread out
What is "changing a solid to a liquid"?
Melting
Particles that are loosely bonded together are in what state of matter?
liquid
______ Energy is another way to discuss temperature.
Thermal
When particles are not in motion, they have _________energy
Potential
What is "changing liquid to a gas"?
Evaporation
How do particles in liquid behave compared to particles in a gas?
Particles move slower in liquid than they do in gas.
or Particles in gas move faster than particles in liquid
(this is because of the breakage in bonds)
If you add ice to boiling water, what would happen to the hot water?
The boiling water would cool down to room temperature (the solid ice would melt)
What affects the movement of particles?
2 parts
Mass
What is "changing from gas to liquid"?
Condensation
What causes particles to move more quickly in a substance?
Adding more energy.
How does weight affect how fast thermal energy changes a phase of matter?
The bigger the object is, the more thermal energy you will need to change the phase of matter
How does temperature affect the movement of molecules?
2 parts
The colder the temperature, the slower molecules move.
