Heat flows through a substance when heat is provided to a substance, the molecules that receives it first gets excited and begins to vibrate to and fro thereby hitting another molecule and transferring this vibration to more molecules thereby transferring the heat energy.
Conduction, convection, and radiation are all types of heat transfer that involve heat flow from objects to colder objects. Conduction is the transfer of heat through a material due to direct contact, convection is the transfer of heat through a fluid (liquid or gas), and radiation is the transfer of heat through electromagnetic waves.
Viscosity can affect heat transfer by influencing the speed at which a fluid flows. Higher viscosity fluids flow more slowly, which can impede heat transfer due to reduced convective heat transfer rates. Conversely, lower viscosity fluids flow more freely, allowing for better heat transfer as they move more easily over a surface.
The opposite of heat transfer is insulation. Insulation helps to reduce the transfer of heat between two surfaces or areas by providing a barrier that limits the flow of heat energy.
No, heat transfer by convection requires the movement of fluids to transfer heat. Since solids do not have the ability to flow like fluids, heat transfer by convection does not typically occur in solids. Heat transfer in solids usually occurs through conduction, where heat is transferred through the vibration of particles.
A sign of heat transfer is when there is a change in temperature. Heat will flow from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached. Temperature difference is a key indicator of heat transfer.
It is heat transfer at speed higher than 0.3 Mach.

A decrease in the overall heat transfer coefficient due to fouling or dirt buildup can reduce the efficiency of heat transfer in a system. This can lead to a decrease in the water flow rate as the system needs to compensate for the reduced heat transfer efficiency. Increased resistance to heat transfer can result in higher energy consumption and reduced performance of the system.

The heat transfer sign convention refers to the direction of heat flow in a system. It impacts the analysis of heat transfer processes by determining whether heat is being gained or lost by a system. This convention helps in understanding the direction of heat transfer and its effects on the system's temperature changes.
The flow of energy due to a temperature difference is called heat transfer. Heat transfer can occur through three main mechanisms: conduction, convection, and radiation.
