TOPIC 1 Flashcards
What does flow mean
- flow means a liquid or gas moving from one place to another
what are the basic building blocks of all materials
- the basic building blocks of all materials are atoms and molecules or known as the particles of matter
what are the three states of matter
- solid
- liquid
- gas
what is a solid? what is an example
- is the state of matter in a substance that has a definite shape. An example would be a sugar cube
what is a liquid? give a example
- is the state of matter of a substance that has a definite volume but no definite shape. An example would be water.
what is a gas? and give an example
is the state of matter of a substance that has neither a definite shape nor definite volume. An example would be oxygen
how do particles in a solid interact with eachother
- they interact by when they are close together and they have no room to move around freely. They can only vibrate.
how do particles inteact in a liquid
the particles that make up a liquid have enough energy to pull away from eachother while at the same time vibrating close in small clusters.
how do particles in a gas interact with eachother
Gas particles are so far apart form eachother that their is an enourmous amount of empty space between them
what is morphing
is a special film effect that mimics the changes we see in the states of matter.
and example is in the terminator when the policman morphs into liquid.
what are changes of state
changes of state occur when the particles of a substance gain or lose energy.
what is this an example of
the particle model
what are plastic shopping bags made out of ?
plastic shopping bags are made out of polyethyne.
why is styrofoam fluffy
it is expanded polystrene The solid plastic contains millions of tiny bubbles of gas or air. It is the bubbles that make it fluffy and a great insulator and shock absorbing material.
what is a thermoplastic
thermoplastic is a type of plastic that becomes soft whem heated and hard when cooled.
