The pressure of air that can support 760 mmHg column at sea level is called one atmosphere. OR It is a force exerted by 76 cm long column of mercury on an area of 1 cm2 at 0°C. Atmospheric Pressure at Sea Level: It is the average pressure of atmosphere at sea level. i.e.; 760…
1. Solids have definite volume and shape. This is because the attractive forces among the particles of solids are very strong. 2. The particles of solids are very close to each other and they are tightly packed. This is why they are non-compressible and they cannot diffuse into each other. 3. The solid particles possess…
Liquids have following properties. 1. Liquids have definite volume. However, they do not have definite shape. 2. The molecules of liquids are in state of constant motion. The evaporation and diffusion of liquids is the result of their motion. 3. The densities of liquids are much greater than those of gases but are closer to…
Gases have following properties. 1. Since gases occupy all the available space, therefore, they do not have definite volume. 2. They do not have a definite shape. 3. The gases bubble through liquids and tend to rise up due to their relatively low densities. 4. Gases can diffuse and effuse. This property is negligible in…
Matter: Anything which possesses mass and occupies space is called matter. States of Matter: Matter exists in 5 states. (i) Solid (More common form of matter) (ii) Liquid (Less common form of matter) (iii) Gas (Simplest form of matter) (iv) Plasma (Advanced form of matter) (v) Bose-Einstein Condensates Definition of state of matter Solid…
