    Study Notes

    Density Calculation

    • Density is calculated using the formula: Density = Mass/Volume
    • An object with a mass of 300g and a volume of 50cm³ has a density of 6g/cm³.

    Changes in Physical Properties

    • A change in only the physical properties of matter includes processes such as melting, freezing, or dissolving, which do not alter the chemical composition.

    Characteristics of Liquids and Solids

    • Both liquids and solids maintain a definite volume, distinguishing them from gases, which do not.

    Behavior of Gas in a Heated Vessel

    • When a closed rigid vessel containing a gas is heated, the pressure of the gas increases due to increased kinetic energy of the gas molecules.

    J.J. Thompson's Discovery

    • J.J. Thompson discovered the electron as a negative particle in atoms when he observed that cathode rays bend positively towards a charged plate, indicating the presence of negatively charged particles.
