The attractive forces between the positive end of one molecule with the negative end of other molecule are called dipole-dipole forces. Explanation: In case of HCl, There is much electronegativity difference between hydrogen and chlorine. Due to this chlorine being more electronegative develops a partial negative charge whereas hydrogen develops partial positive charge. Hence the…
Intermolecular Forces Definition Chemistry: The attractive forces that exist between the individual particles (molecules, atoms or ions) are called intermolecular forces. (Van der Waals’ forces). The physical state of a substance depends on the strength of intermolecular forces. The properties of liquids such as boiling point, heat of vaporization, vapour pressure, surface tension and viscosity…
Following statement of Charles’ law helps to derive absolute zero of temperature. “At constant pressure the volume of a given mass of an ideal gas increases or decreases by 1/273 of its original volume at 0°C for every 1°C rise or fall in temperature respectively.” ABSOLUTE ZERO TEMPERATURE Definition: The temperature at which volume of…
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…
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…
