Dissolved substances diffuse throughout a liquid As the mobile particles of the liquid can move, they carry the dissolved substances.
Ohm's law, voltage, current and resistance Electric Circuits in Series: Classical mechanics - covering Newton's Laws, velocity, acceleration, force, energy, momentum, impulse, moments and torques. A gas is easily compressed. Nuclear Fission and Radioactivity - Part 2 of 3 Describes the process of radioactive decay and nuclear fission including the calculation of half lives.
Slightly further apart than in solid phase. Evaporation Evaporation is the change in state from a liquid to a gas at a temperature below its boiling point.
Alkenes are formed in cracking. Carbon dioxide will turn limewater milky. Hubble, Big Bang and The Age of the Universe - Part 3 The derivation of Hubble's equation from the Doppler effect, the deduction of an expanding universe from a Big Bang and a calculation of the age of the universe.
Telecommunications - A Level Physics A description of telecommunications: The GCSE playlist, A Level playlist and associated A level Questions playlist at best form material suitable for revision where the full course has already been taught. Imagine a model of Britain in which every model person also had a model of Britain and each of these tiny model people also had a model of Britain with the right number of little people.
How Big is the Universe? These help us to understand the way in which matter is constructed the particulate nature of matter. Carbohydrate Metabolism Regulation by University of Arizona Learn about the regulation of carbohydrate metabolism by insulin, glucagon and epinephrine, mainly in liver and muscle.
Gas to liquid is called condensation. Large hydrocarbon molecule be cracked in an oil refinery by thermal decomposition reaction in which large molecule split apart to form smaller, more useful ones.
Why is cracking so important? Resistances in Parallel Electrical Power: Real and virtual images.
In physics, you are most likely to need to be able to explain that the transfer of energy by conduction, convection, evaporation and condensation involves particles, and how this transfer takes place.
Circular Motion - A Level Physics Consideration of Circular Motion, orbital speed, angular speed, centripetal acceleration and force - with some worked examples Friction - A Level Physics A description of friction, the coefficient of friction and friction on an inclined plane. I do not envisage that these videos should replace a course of proper instruction.
As you might imagine from the name of this theory, it is all about movement of particles. It does not follow a particular Board's syllabus.Summary notes, revision videos and past exam questions by topic for Edexcel IGCSE Physics Topic 5 - Solids, Liquids and Gases.
Section 3 Waves. Notes. Oscilloscope wave traces. If a microphone is connected to an oscilloscope, the sound received by the microphone is transferred electrically and the oscilloscope trace can be used to compare frequency (pitch) and amplitude (loudness).
The diagrams show graphical representations of sound waves as seen on an oscilloscope. Define the palmolive2day.com of liquids and palmolive2day.com of solids. Why is it important to determine these physical properties of a substance?
Why is it important to determine these physical properties of a substance? The melting point of a solid is the point at which a solid becomes a liquid with standard atmospheric pressure. CGP write and sell great value revision guides and study books for UK schools.
The educational books cover A-Level, GCSE, KS3, KS2 and KS1 with subjects such as Maths, Science, History, Geography, French, English and more.
Order online! States of matter Solids, Liquids, gases. Changes of state.
Differentiated worksheets. I wrote these for a lower ability GCSE group but they could easily be used for KS3. The higher and lower ability worksheet have a mark scheme on the second page.
