Chapter 6- Material Properties Flashcards
What is the practical theory state
Practical theory states that materials are made of particles that are so tiny they cannot be seen a naked eye
What particles are particularly of the Particle theory
Atoms and molecules
Explain a the particles in solids
The particles in a solid I hope together by strong forces, the particles cannot change position in the skiff solids a fixed shape and Definite volume, and makes them harder to squish, the particles however can vibrate a little and they fixed position
Explain the particles in liquids
The particles in liquids I had to get a bye week forces so they can slide over each other, this gives liquid a definite volume and makes them hard to Squash, but allows them to flow and take up the shape of any container to which they are poured.
Explain the particles in gases
Gases have very small forces between them, so the particles can move freely and all directions. This allows guests to flow easily, be squashed easily, change the volume and take out the shape of the containers.
Describe the three states of Matters particle arrangement
Solid, equally distanced, Organized, looks like A side of a Rubik’s cube
Liquid, not equally spaced, no quite close together very messy
Yes, not organized, spread out
Explain the changes of state between different states of matter
Heating a solid two it’s melting point changes it to a liquid this process is called melting
Heating a liquid to It’s boiling point changes it into a gas this process is called boiling
Cooling a liquid to a certain temperature can turn it in to a solid this is called condensing
Changing a liquid to a gas is called evaporation
What is a gas made of
Millions of quickly moving particles which brands of the walls of the container
How do you raise the gas pressure
You heat up the gas so that the The gas receives more energy moves faster and bounces more frequently
How do you lower the gas pressure
You call the gas switch makes the gas particles move slower and bounce less frequently off the walls of its container
What is diffusion
Diffusion is a process in which one substance spreads through another it can occur when two or more liquids or two more guesses meat
How do you speed up diffusion and gases?
You make the room temperature increase
Why is the fusion foster and and
Because gas particles move faster than particles in a liquid
