classification of matter using mapping

Today the fact that all matter is made up of atoms is universally accepted. Realisation of the atomic constituents of matter began in 1828 when Scottish botanist Robert Brown observed a random ceaseless motion of pollen grains suspended in a liquid. Many macroscopic proper..

Introduction - Today the fact that all matter is made up of atoms is universally accepted. Realisation of the atomic constituents of matter began in 1828 when Scottish botanist Robert Brown observed a random ceaseless motion of pollen grains suspended in a liquid. Many macroscop..

>This is called as dual nature of mater. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be associated with a definite amount of ene..

A pictorial representation that gives the direction of the magnetic field at various points in a magnetic field is called a map of the magnetic field Let us now map the magnetic field by using a compass Fix a sheet of paper on a drawing board Place a bar mag..

Introduction - The first magnetic phenomenon observed were those associated with naturally occurring magnets, fragments of iron ore found near the ancient city of Magnesia. These attracted unmagnetised iron. The attraction was maximum at certain regions of the magnet called the poles. The Chinese h..

The points on the map represent the important places of Sicilia, Italy. Use the map to select the choices that are collinear. => Palermo, Enna, Catania or Trapani, Caltaniss, Rigasa or Messina, Catania, Siracusa or Agrigento, Caltaniss, Enna..

Summary - The phenomenon of interference, diffraction and polarization can be explained by the wave theory of light. But the photo electric effect can be explained only using 'photon theory'. That is using particle nature of light. The experimental study of photoelectric effect ..

A map is drawn using a scale of 1 inch : 4 meters. If the length of a bridge on the map is 20 inches, then find the actual length of the bridge. => 80 meters or 77 meters or 81 meters or 79 meters..

A map company used a scale of 1 inch : 130 miles to depict the lengths of different lakes. What is the length of a lake on map, which is actually 780 miles long? => 7 inches or 9 inches or 8 inches or 6 inches..
