Matter

MATTER


Matter is anything that occupies space and has mass. Everything that exists in this universe is matter. The matter is made up of tiny particles known as atoms. It is usually found in 3 states(solid, liquid &gas).

Properties Of Matter

1) Matter is made up of particles:-

       Matter is made up of small particles known as atoms. These atoms join together to form molecules . 

2) Particles of matter have space between them:-

     Particles of matter have space between them which is known as intermolecular space.

3)Particles of matter attract each other:-

     Every particle of matter applies an attractive force on other particles. This means that every particle of matter      pulls the other particle toward itself. This force of attraction is known as inter-molecular-force of attraction.

4)Particles of matter are in continuous motion:-

     Particles of matter move continuously. The particles of matter move because they have kinetic energy.

States Of Matter


Matter is found generally in 3 stages at room temperature i.e. solid, liquid & gas. There are other two states of matter known as the BEC (Bose-Einstein condensate) and plasma. The states of matter usually depend on:-
  • The intermolecular force of attraction.
  • Inter-molecular space.

Solid

  • It is the state of matter with highest inter-molecular force and lowest intermolecular force of attraction.
  • The particles of solid have very low kinetic energy that is why they don't move. They vibrate at their own place.
  • Solids have a fixed shape and volume.

Liquid

  • It is the state of matter with moderate (between that of solid and liquid) intermolecular force and molecular force of attraction.
  • The particles of solid have moderate kinetic energy, they can move. 
  • Liquids have a fixed volume but not a fixed shape. 

Gas

  • It is the state of matter with lowest intermolecular force and highest intermolecular force of attraction.
  • The particles of solid have very high kinetic energy. 
  • Gases don't have a fixed shape and volume.

Animal and Plant Cells

 Cells Cells are the basic functional, biological and structural unit of life. The word cell is a Latin word meaning ‘small room’. Cells are also known as building blocks of life.  The branch of science that deals with the form, structure, and composition of a cell is known as Cytology. All organisms around us are made up of cells. Bacteria, ameba, paramecium, algae, fungi, plants and animals are made up of cells.  Cells together form tissues. And tissue together makes an organ. History Of Cell The cell was discovered by Robert Hooke in 1665. He assembled a simple microscope and observed a very thin slice of cork under his primitive microscope. The cork was obtained from the outer covering of a tree called bark. Robert Hooke observed many little-partitioned boxes or compartments in the cork slice. These boxes appeared like a honey-comb. He termed these boxes as the cell. He also noticed that one box was separated from another by a wall. What Ho

Rutherford Alpha Ray Scattering Experiment

Rutherford Alpha Ray Scattering Experiment Hey, Guys, most of you might have heard about the alpha ray scattering experiment and if you want to know in detail about Rutherford's model and the experiment he conducted, this is the right place for you... But first: Things You Must Know Some basic information that will help you understand rutherford experiment properly: Proton is a sub-atomic particle which is positively charged and has a mass of 1u. Alpha particles are helium atom with a charge of +2 as they have lost 2 electrons. Alpha particles have an atomic mass  of 4u. Gold is highly malleable and can be beaten into very thin sheets. Experiment Rutherford conducted his experiment in the following way: Rutherford took a very thin gold foil and bombarded it with high energy alpha particles. He placed a layer of zinc sulphide on the walls where the experiment was taking place because when alpha particles strike zinc sulphide layer, it results i

Isotopes, Isobars and Isotones

Isotopes These are elements which have the same atomic number but different atomic mass . They have the same atomic number because the number of protons that are inside their nuclei remains the same. But, they have different atomic mass because the number of neutrons that are also inside their nuclei is different. As the number of protons inside nuclei remains same, therefore the overall charge of the elements also remains same as in isotopes: no of protons = no of electrons . Hence, as isotopes overall charge remains neutral, therefore their chemical properties will also remain identical.   Therefore, Isotopes are chemically same but physically different.

Cathode Ray Experiment

This experiment was conducted by J.J. Thomson (Sir Joseph John Thomson) in the year 1897. This experiment proved that atom is made up of fundamental particles which are much smaller than the smallest atom 'hydrogen' This experiment helped to discover electron. According to J.J. Thomson, the cathode rays consisted of very light, small and negatively charged particles. He named the particles "corpuscles" which were later known as electrons
