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.
