What energy transfer is important to thermography?
When there is a temperature difference between two objects or two areas within the same object, heat transfer occurs. Heat energy transfers from the warmer areas to the cooler areas until thermal equilibrium is reached. This is the Second Law of Thermodynamics.
What is the thermal transfer of energy?
Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, convection involves the movement of warm particles and radiation involves the movement of electromagnetic waves.
What type of energy transfer is necessary for infrared photography?
What type of energy transfer is necessary for infrared photography? Explain your answer. Conduction Thermal energy is transferred between particles through conduction. In this example, the candle is warming one end of the metal bar.
What type of energy transfer is radiation?
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
What is infrared thermography used for?
IR thermography is a form of nondestructive testing that measures temperature variances of a component as heat (i.e. thermal radiation) flows through, from, or to that component. IR thermography is also generically known as IR testing, thermal testing, thermal imaging, and IR thermometry.
What is thermography in chemistry?
Thermography is the process of using an infrared camera to look for abnormally hot or cold areas on a component operating under normal conditions. It is a viable nondestructive evaluation technique for the characterization of corrosion in metallic materials and is the simplest of all thermal inspection techniques.
