Particle Theory of Matter
State the Three states of Matter?
Solid, Gas, Liquid.
True or false: Does mass change when a gas is being heated
False
What is Density?
A measure of how much “stuff” or mass is packed into a certain amount of space, or space
What does boiling do to the particles?
Boiling causes the particles to move around rapidly spreading them, which causes them to collide.
What is mass?
A measure of the amount of matter in an object
What is matter?
Anything that has mass and takes up space
How come sea levels are rising?
Because of thermal expansion.
When water freezes what pattern does it make?
It makes an Hexagonal pattern
What does freezing rain mean? (complete definition)
Rain that has changed state once it has changed state once it has hit the ground.
True or false: does Volume change when phase change occurs
True
What makes an Solid?
Particles are very strongly attracted to each other. Locked in a patten and vibrate in place fixed shape.
What happens when a solid is being heated
Particles get boosted and they start to vibrate.
What makes water special?
It expands and takes up more space
It is less dense in its solid form than in its liquid form
What product does glycol go into (which freezes at -20C)?
Glycol goes into antifreeze which is used to defrost windows, sidewalks and more.
What is volume
The amount of space matter takes up
Why are the particles of matter Always moving
It is because of the kinetic energy
What happens when a gas begins to get heated.
The heat causes the particles to spread out and evaporate.
A blanket can also be defined as?
An insulator
What happens to molecules during a freezing state?
The molecules group together causing them to join together holding them into a fixed shape.
What degree does it have to be for evaporation to occur?
100 degrees
What is the particle theory of matter
It is everything that has particles in it
What is the liquid inside a thermometer?
Mercury or alcohol
Why doesn’t the body of water freeze solid
The ice layer on top acts like blanket providing insulation
What is the boiling point for Ethanol?
The boiling point for Ethonal is 78.5 degrees celsius.
What is the Principle of Conservation of Mass?
The total mass of substances doesn’t change during a chemical reaction
