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).
