States of matter
Changes of state
Heat & Temperature
100
Forms of matter that can flow, the mass of a given volume.
What are fluids and density?
100
anything with mass and volume
What is matter?
100
solids, liquids, gases, and plasma
What are the four states of matter?
100
Melting, evaporation, sublimation
What are the changes of state that happen when energy is added?
200
water and gas
What states of matter can flow?
200
the quantity an object has, the space it takes up
What is mass and volume?
200
packed together and vibrating, these particles have a set volume and shape.
What are solids?
200
Condesation, solidification, depostion
What are the changes of state that occur when energy is released?
200
The particles move faster, and the material expands/increases in volume when energy is added
What is thermal expansion?
300
a model that explains what happens to particles when the energy changes
What is the Kinetic Molecular Theory?
300
set volume but no set shape, far apart enough to slide past each other
What is liquid, and how do its particles act?
300
the temperature at which solid turns to liquid, the temperature at which liquid turns to gas
What is the melting point and the boiling point?
300
the movement of particles slows down and the material takes up less space/contracts when energy is taken away
What is thermal contraction?
400
1. all matter is made of tiny particles (molecules and atoms) 2. there is empty space between the particles 3. particles are constantly moving, colliding with each other and their surroundings, 4. energy makes particles move, the more they have the faster/farther apart they get
What are the main points of the Kinetic Molecular Theory?
400
bouncing off each other and surroundings, no fixed shape or volume
How do gas particles act, and what is it?
400
dry ice
What is an example of sublimation?
400
The energy transfered from one material to another; the average kinetic energy of its particles
What is heat and temperature?
500
The amount of space an object take up when placed in fluid
What is displacement?
500
the type of particle.
What determines the strength of attraction in particles?
500
charged, far apart and moving fast, violently colliding with each other/enviroment
How do the particles in plasma move?
500
the particles become more energetic and move farther apart
What happens if temperature is raised?
500
energy will always flow from high to low
How does energy transfer between two objects with different temperatures?
