What we have learnt
- Thermodynamics involves the study of heat and temperature and their relationship with energy.
- Heat is energy in transit and temperature is a measure of thermal state, with distinct units for each.
- Thermal expansion leads to changes in dimensions based on temperature variations, impacting everyday structures.
Key Concepts
- -- Thermodynamics
- The branch of physics that studies the relationship between heat, temperature, and energy conversion.
- -- Heat
- A form of energy transferred from one body to another as a result of a temperature difference.
- -- Temperature
- A measure of the average kinetic energy of particles in a substance, indicating hotness or coldness.
- -- Specific Heat Capacity
- The amount of heat required to raise the temperature of 1 kg of a substance by 1°C.
- -- Latent Heat
- The heat energy required for a substance to change its state without changing its temperature.
- -- Modes of Heat Transfer
- The methods by which heat energy moves, including conduction, convection, and radiation.
