What we have learnt
- Thermal energy is the total kinetic energy of particles in a substance, while temperature measures the average kinetic energy.
- Heat transfer occurs through conduction, convection, and radiation, each with distinct mechanisms and materials involved.
- The understanding of specific heat capacity is crucial for predicting how materials respond to heat, which has practical applications in insulation and energy consumption.
Key Concepts
- -- Thermal Energy
- The total kinetic energy of all particles in a substance, which influences temperature and heat transfer.
- -- Specific Heat Capacity
- The amount of heat energy required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.
- -- Conduction
- The transfer of heat through direct contact between particles, primarily occurring in solids.
- -- Convection
- The transfer of heat through the movement of fluids (liquids and gases), creating convection currents.
- -- Radiation
- The transfer of heat through electromagnetic waves, which can occur in a vacuum.
