    Study Notes

    Energy and Systems

    • When a liquid or solid is dissolved in water at a high temperature, it can't maintain equilibrium, resulting in heat loss, following the law of conservation of total energy.

    Heat Transfer

    • Example: 100g of H2SO4 was added to water, causing the temperature to rise by 10°C.

    Specific Heat Capacity

    • Specific heat capacity of water is 4.18 x 10^3 J/kg°C.
    • Specific heat capacity is the amount of heat energy required to raise the temperature of 1kg of a substance by 1°C.

    Systems

    • There are three types of systems:
      • Open system: exchanges both matter and energy with its surroundings (e.g., a hot cup of coffee).
      • Closed system: exchanges energy but not matter with its surroundings (e.g., a sealed container of hot water).
      • Isolated system: exchanges neither matter nor energy with its surroundings (e.g., a thermos flask).
