The particles of which the matter is comprised influence its state and properties (physical and chemical). Pay Now | Contact Us | subject, Maximum force of attraction between particles, Less forces of attraction between particles compare to solid, Negligible force of attraction between particles, Kinetic energy of particles is more than solid, Particles cannnot move rather they vibrate only at their fixed  position, Particles have more space and thus can evaporate easily, Kinetic energy among the particles increases, Water content in air increases and so evaporation decreases, Water vapours are blown away by winds allowing more evaporation, Structural Organisation in Plants and Animals, French Southern and Antarctic Lands (+262), United state Miscellaneous Pacific Islands (+1). Also it offers course materials for different Competitive exams like NTSE, KVPY, various Olympiads etc. Therefore, the particles move around freely at high speed and there is no fixed shape of gases. Based on this criterion, we can say that matter is present in three different states: solid state, liquid state, and gaseous state. Matter can be defined as anything that occupies space possesses mass, offers resistance and can be felt by one or more of our senses. Particle nature of Matter *** Advertisement.

The absorption of heat from the surrounding makes the surrounding cool. Diffusion – The process of mixing two different types of particles together is called diffusion. It is a state of matter in which the particles are super excited and super energetic. CBSE Revision Notes Class 9 Science Chapter 1 Matter in Our Surroundings are provided to help the students understand and revise the concepts right from the beginning. As electricity is passed in the tube or the bulb, these gases get ionized and this creates the plasma inside them that glows. By applying pressure, we can bring the particles of matter close to each other thereby, increasing the force of attraction among the particles. Diffusion becomes faster on heating. Chapter 1 Matter in Our Surroundings.

Matter in Our Surroundings Class 9 Notes – Here We have provided summary and revision notes for Class 9 Science Chapter 1. Particles of matter are moving all the time, 3. Therefore, the particles absorb energy from the surroundings in order to compensate the energy that is being lost in the process of evaporation. For example, on dissolving sugar in water, there is no rise in water level because the particles of sugar get into the interparticle spaces between the water particles. number, Please choose the valid Particles of liquids arrange each other is not fixed. The boiling point of a liquid is defined as the temperature at which the vapour pressure of the liquid is equal to the atmospheric pressure. IX Biology Term-1.
