Diffusion: Revision Notes
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration. Diffusion occurs in liquids and gases when their particles collide randomly and spread out.

In order to understand anything in algebra, you have to have an understanding of what a term is. Terms are the building blocks of algebraic equations.
The mitosis process produces two identical diploid cells for the purpose of growth and repair after cell division.
The osmosis process involves the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low concentration.
By moving through the cell membrane, substances can enter and leave the cell. Three of the most common types of movement are diffusion, osmosis, and active transport.
To get you introduced to percentages, we will go through 3 different types of percentage questions that come up in GCSE Maths.
Microscopy is an essential tool for scientific research and analysis, allowing us to observe and study objects that are too small to be seen with the naked eye. GCSE Science students must understand the principles of microscopy and the different types of microscopes and their uses.
Our platform has been built for students like you in Secondary Schools, year 7 to year 11, studying towards your GCSEs. The programme is organised around GCSE syllabuses, focusing on completing all the topics in the syllabus in time for your exams.
School students and teenagers face pressures and stress just like adults. GCSE exams can place a lot of pressure on students and understanding the pressures faced by students and knowing how to deal with it will help you cope better with your GCSE 9-1 exam.
You probably know by now (through your studies of chemistry) that electrons are the âmagicâ behind chemical reactions. They do all the hard work â moving here, moving there, joining this atom, leaving that atom, forming bonds, etc.
If youâre taking a chemistry class or even a general science class, chances are pretty good that you have a copy of the Periodic Table of Elements.
Whether primary or secondary, historical sources are imperative if we are to gain a clear understanding of the events that shaped the lives that we lead today.
Numbers are symbols we use to count things. Numbers have been in use since the antiquity. We canât live a normal life without numbers. We canât even order a pizza, say our age or count the money without knowing the numbers.
