Study Notes
Thermal Energy
- Heat is a form of energy transferred between objects at different temperatures.
- Temperature measures the average kinetic energy of the particles.
- Heat capacity is the amount of heat needed to raise the temperature of a substance by one degree Celsius.
- Specific heat capacity is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.
- Thermal energy exchange occurs when heat flows from a hotter object to a colder object until they reach thermal equilibrium.
Heat Transfer
- Three main methods of heat transfer: conduction, convection, radiation.
- Conduction: Heat transfer through direct contact.
- Convection: Heat transfer through the movement of fluids (liquids and gases).
- Radiation: Heat transfer through electromagnetic waves.
Latent Heat
- Latent heat of fusion is the heat absorbed or released during a phase change between solid and liquid.
- Latent heat of vaporization is the heat absorbed or released during a phase change between liquid and gas.
Nuclear Radiation
- Nuclear radiation involves the emission of particles or energy from unstable atomic nuclei.
- Ionizing radiation has enough energy to remove electrons from atoms, potentially causing damage to living tissue.
- Alpha decay: Emission of an alpha particle (helium nucleus).
- Beta decay: Emission of a beta particle (electron or positron).
- Gamma decay: Emission of gamma rays (high-energy photons).
