Conduction Conduction is the transfer of thermal energy from one place to another without any flow of the material medium. Thermal Conductors & Thermal Insulators Metals are good thermal conductors. Non-metals are poor thermal conductors.(they are thermal insulators) Good thermal conductors (e.g. metals) feel colder than thermal insulators (e.g. plastics) in an air-conditioned room, even though they are at the …
A gas, made up of many particles called molecules that are in continuous random motion, colliding with one another and with the walls of the container. As the gas molecules strike and bounce off the walls, they exert a force on the walls. All these small forces add up so that a large number of collisions produces a total average …
Brownian Motion Brownian motion is the random and irregular motion of gas and liquid molecules. Brownian motion provides clear evidence for the kinetic molecular model of matter in that matter is comprised of tiny particles that are in continuous random motion, with a range of speeds n all directions and kinetic energies. In the simulation above, it is seen that …
The three states of matter are solid, liquid and gas. Solid Solids have strong atomic bonding and high viscosity, resulting in high density, highly incompressible and hence, an inflexible shape. The atoms/molecules in a solid are closely packed together and occupy minimum space, usually in a regular pattern. Due to strong intermolecular attractive and repulsive forces, motion is limited to …
Wave Wave is defined as the propagation of periodic disturbances from one region to another, without the transfer of any material medium. Waves provide a mechanism for the transfer of energy from one point to another, there is no transfer of any material between the points. Classifications Of Waves Waves can be classified as: Mechanical Electromagnetic Transverse Longitudinal Progressive (Travelling) …
This topic covers “General Wave Properties” of O Level Physics (Equivalent to American high school diploma). This topic covers the basic definition of waves, their inherent properties, and introduces the practical aspect of studying waves through a ripple tank. Join us in unraveling the essence of wave dynamics and observing their fascinating behaviors in this concise exploration. If this is …
Uses of Radiation Radiation, a form of energy emitted in the form of waves or particles, finds application in a wide array of fields ranging from medical treatments to archaeological discoveries. Its use in modern technology and research has brought about significant advancements and innovations. Below, we delve into some of the primary uses of radiation, highlighting its importance and …
