Heat transfer is the physical act of thermal energy being exchanged between two systems by dissipating heat. Temperature and the flow of heat are the basic principles of heat transfer. The amount of ...

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research.

Editor’s note: The KOIN 6 Weather team is presenting weather and science lessons to help serve our teachers and students. Click here for more lessons. PORTLAND, Ore. (KOIN) – We’re heating up the ...

Fundamentals of heat transfer by conduction, convection, radiation. Steady and transient heat conduction in solids. Forced and free convection in fluids. properties of thermal radiation. Radiation ...

Continuing the heat transfer series, in this video we take a look at conduction and the heat equation. Fourier's law is used to calculate the rate at which heat is transferred through an object due to ...

There are various things we need for survival. Like water, food and energy. On the last point, our primary source of energy is the Sun, but our relationship with it can only be described as delicate.

Heat is transferred by radiation between two well-separated bodies at temperatures of finite difference in vacuum. At large distances the heat transfer can be described by black body radiation, at ...

When the free electrons absorb heat energy, they move much faster. As they move through the metal, free electrons crash into metal ions. This process is very much faster than conduction caused by just ...

When the separation of two surfaces approaches sub-nanometre scale, the boundary between the two most fundamental heat transfer modes, heat conduction by phonons and radiation by photons, is blurred.
