All of these follow the properties of solids. Also it offers course materials for different Competitive exams like NTSE, KVPY, various Olympiads etc. Refund Policy. Therefore, the interparticle force of attraction between the particles reduces and particles get detached from their position and begin to move freely. This means there are millions of particles present in the color which just divide themselves on dilution. Diffusion refers to the process of mixing of different particles of substances. As electricity is passed in the tube or the bulb, these gases get ionized and this creates the plasma inside them that glows. The heat energy is therefore considered as hidden. Yes, other matter can diffuse into liquids whether it is solids, liquids, or gases. Matter is particulate in nature. When the particles of matter intermix on their own with each other, the phenomenon is called diffusion. Evaporation – The phenomenon of change of a liquid into vapors at any given temperature below its boiling point is called Evaporation. (i) For example, the gradual drying of damp clothes is caused by the evaporation of water to water vapour. Matter is anything that has mass and occupies space. There are water vapours present in the air. Please choose a valid This happens because the particles of red color mix with the particles of water. The process of evaporation uses the energy of the liquid particles. Franchisee | We can arrange the force of attraction between different types of matter (solids, liquids, and gases) in increasing order as: We can also move our hands through water or liquid matter but not as freely as we can in the air. Required fields are marked *. By applying pressure, the interparticle spaces between particles of matter decreases. Matter … 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. Learning the important concepts is very important for every student to get better marks in examinations. It occurs because of the movement of molecules in matter. It includes all the topics given in NCERT class 9 Science text book. →This is because the force of attraction between particles of gas is almost negligible, in liquid the forces of attraction is moderate but it is greatest in solid. Therefore, there is a space between the particles of liquids and they can flow easily. BEC is formed by condensing gases of extremely low densities to much lower temperatures.
