What is on the 5 senses and written notes/sketches?
400

400
description of placement of particles in solids, liquids and gases
What is densely, closely packed, more spaced apart and widely spaced apart, by particle theory?
500
Archimedes Principle
What is buoyant force on object immersed in liquid equals weight of the fluid displaced?
500
how particle theory explains which flows faster, water or air
What is air because it is a gas, and the particles are spaced widely apart and flow the most freely?
500
explains why fish don't die in winter in Haliburton lakes
What is water is most dense and a liquid at 4 degrees celcius and therefore sinks to the bottom; ice floats on the top?
