The heat transfer depends on the factors such as the amount of time of contact, the area of contact, and the specific heals of the substances.
The process of flow of energy from a body of higher temperature to a lower temperature is known as heat transfer.
The mathematical expressions governing the concept of heat transfer are given as follows-
Q = m × c × ΔT
here,
m is the mass of the body.
c is the specific heat.
ΔT is the change in temperature.
And,
Q = k × A×ΔT / L
here,
k is the thermal conductivity.
A is the area of contact and L is the length of the body.
So, clearly, heat transfer depends on the factors such as specific heat and the area of contact. Moreover, the time of contact is also a matter of discussion as the longer the contact time, the more amount of energy will get a transfer from one body to another.
Thus, we can conclude that the heat transfer depends on the factors such as the amount of time of contact, the area of contact, and the specific heals of the substances.
