Revising States of matter with quizzes
(Simple states of matter quizzes for students going in for the GCE, GCSE, and necta)
Welcome to gcequiz platform, the perfect place to test your knowledge. This is an online revision platform that tests your knowledge by providing you with thousands of quizzes to answer., These quizzes have been set based on the GCE and GCSE curriculum. If you have any issues revising, then answering the quizzes on this website is the best way to start revising.
In this section, our topic of study is states of matter. We'll be describing the various states such as the solid state, liquid state, and gaseous state. Quizzes on states of matter are made available below. First of all, let's have a recap of our topic:
Matter can be defined as anything that has mass and occupies space. Matter exists in many states. ie solid, liquid, gas, and plasma. A state of matter is one of the distinctive forms in which matter can exist. Below are the fundamental states of matter:
Solid: In solids, the constituent particles which could be ions, atoms, or molecules are closely packed together. The forces that exist between these particles are very strong in such a way that the particles cannot move freely but can only vibrate. Hence, a solid has a stable definite shape, volume and can only change shape when an external force acts on it and gets it deformed, broken, or cut.
Liquids: Liquids are almost incompressible fluids, and they take the shape of the container in which they are put but retain an almost constant volume that is independent of pressure. The intermolecular forces between the liquid molecules are not as strong as the forces between solid particles.
Gases: Gases are compressible fluids that will conform to the shape of their containers and also expand to fill the container. Gas molecules have enough kinetic energy, making their intermolecular forces small (or zero for ideal gases).
Plasma: Similar to gas, plasma does not have a definite shape or volume. They are electrically conductive and they also produce magnetic fields and electric current, responding very strongly to electromagnetic forces.
During the exams, students are expected to be able to describe and illustrate the various states of matter. They are expected to master the concept well so as to get a good pass in questions asked on this topic. For more entertaining quizzes, click here.
