Slide 1 : WELCOME
Slide 2 : PHYSICAL NATURE AND CHARACTERISTICS OF MATTER
MATTER : MATTER MATTER IS ANYTHING THAT HAS MASS AND TAKES UP SPACE OR OCCUPIES VOLUME
CLASSIFICATION OF MATTER : CLASSIFICATION OF MATTER * Physical classification of matter-based on the physical nature of matter
* Chemical classification of matter-based on the chemical nature of matter
PHYSICAL NATURE OF MATTER : PHYSICAL NATURE OF MATTER Matter is made up of particles
PARTICLES OF MATTER ARE VERY SMALL IN SIZE : PARTICLES OF MATTER ARE VERY SMALL IN SIZE
MATTER IS MADE UP OF PARTICLES WHICH ARE VERY SMALL IN SIZE AND ARE NOT VISIBLE TO THE NAKED EYE : MATTER IS MADE UP OF PARTICLES WHICH ARE VERY SMALL IN SIZE AND ARE NOT VISIBLE TO THE NAKED EYE
MATTER AROUND US EXISTS IN THREE STATES : MATTER AROUND US EXISTS IN THREE STATES SOLID LIQUID GAS
CHARACTERISTICS OF PARTICLES OF MATTER : CHARACTERISTICS OF PARTICLES OF MATTER Particles of matter have space between them
Particles of matter are continuously moving
Particles of matter attracts each other
PARTICLES OF MATTER HAVE SPACE BETWEEN THEM : PARTICLES OF MATTER HAVE SPACE BETWEEN THEM
SPACING IS IN THE ORDER OF : SPACING IS IN THE ORDER OF GAS > LIQUID > SOLID
PARTICLES OF MATTER ARE IN CONTINUOUS MOTION : PARTICLES OF MATTER ARE IN CONTINUOUS MOTION
SPEED OF MOTION OF PARTICLES IS IN THE ORDER OF : SPEED OF MOTION OF PARTICLES IS IN THE ORDER OF GAS > LIQUID > SOLID
AS THE TEMPERATURE RISES PARTICLES MOVES FASTER : AS THE TEMPERATURE RISES PARTICLES MOVES FASTER SUGAR DISSOLVES SLOWLY
IN COLD WATER SUGAR DISSOLVES FASTLY
IN HOT WATER COLD WATER HOT WATER
PARTICLES OF MATTER ATTRACTS EACH OTHER : PARTICLES OF MATTER ATTRACTS EACH OTHER Chalk piece breaks easily Iron ball does not breaks
FORCE OF ATTRACTION VARIES FROM MATTER TO MATTER : FORCE OF ATTRACTION VARIES FROM MATTER TO MATTER Particles attracts strongly
Not easy to break the chain Particles attracts weakly
Easy to break the chain
FORCE OF ATTRACTION IS OF THE ORDER : FORCE OF ATTRACTION IS OF THE ORDER SOLID> LIQUID>GAS
WHAT YOU HAVE LEARNED? : WHAT YOU HAVE LEARNED? * All substances present in the universe that has mass and occupies volume are called matter
* Matter is made up of large amount of particles which are very small in size
* Matter around us exists in three different states-
solid , liquid and gas * Particles of matter have space between them
* Particles of matter are continuously moving
* Particles of matter attracts each other
Which of the following are matter? : Which of the following are matter? (a) Chair
(b)Air
(c)Love
(e)hate
(f)Almonds
(g)Thought
(h)Cold
(i)Cold drink
(j)Smell of perfume
* When temperature is increased, the kinetic energy of the particles of matter : * When temperature is increased, the kinetic energy of the particles of matter (a) decreases
(b) increases
(c) remains constant
Ans : increases
Give reasons… : Give reasons… 1. A gas fills completely the big vessel in which it is kept .
2. Water at room temperature is a liquid .
