Which of the following is not a method of heat transfer? Conduction Insulation Radiation Convection
Answer:
insulation is the correct answer
The method that is not one of the heat transfer method is insulation.
Heat transfer can be regarded a term in thermal engineering use to describe the generation as well as the use and conversion, exchange of thermal energy that exist between physical systems. Heat transfer can be done with different mechanismsThese are: conductionconvectionRadiationConvection can be regarded as the flow of heat in fluids, these fluids could be warmed gas, water.Conduction can be regarded as the movement of heat through objects that are in physical contact, like two metalsRadiation can be regarded as the energy which appears from a source then travels through space, this do contain wave-like properties. Insulation can be regarded as setting up a barrier between two objects, usually between hot and the cold object , so that heat reduction can be achieved.Therefore, Insulation is not heat transfer mechanism, it i a way to reduce heat loss.
