Heat or electrical transfer by contact refers to the transfer of heat or electricity between two objects that are in direct physical contact with each other. This transfer occurs through the vibration of particles within the materials, leading to a flow of energy from a higher temperature or voltage to a lower temperature or voltage.
A toaster transfers heat through electrical coils or elements inside the toaster. When electrical current flows through the coils or elements, they heat up and transfer that heat to the bread placed inside, toasting it.
The energy transfer taking place as the coils in a toaster heat is primarily through conduction. The electrical energy is converted to heat energy in the coils, which is then transferred to the surrounding air and bread slices through direct contact.
Heat energy transfer through direct contact is known as conduction. It occurs when heat is transferred from one object to another by direct contact between the two objects. The transfer of heat occurs through the vibration and collision of particles within the materials.
One method of transfer that does not require contact is through radiation. Radiation is the transfer of energy in the form of electromagnetic waves, such as light or heat, without the need for physical contact between objects.
conduction is the transfer of heat between two surfaces in contact with each other convection is the transfer of heat into a moving fluid radiation is the transfer of heat via electromagnetic waves
Conduction
The transfer of heat through direct contact is called conduction.
Conduction is the term for heat transfer because of direct contact.
