First law of thermodynamics and the law of conservation of energy!

The first law of thermodynamics actually is the variant of the law of conservation of energy. Thus, the first law of thermodynamics second and third just modified for thermodynamic systems. All laws can be interpreted in many ways in relation to physics and chemistry. First, we need to see that the law of conservation of energy all and then we can talk about the first law of thermodynamics. According to the law of conservation of energy, all the energy of an isolated system is constant. Energy can only be transformed, not created or destroyed.

The first law of thermodynamics the energy change of a closed or open system. Considering the thermodynamic process of the present Law are used the concepts of internal energy, work and heat. But when we talk about heat engines, the discussion can go on forever.

Thus, the first law of thermodynamics says that the energy change of a closed system is equal to the amount of heat supplied to the system, so that the amount of heat minus the work the system is the energy change. The standard Unit of measure for these values is measured in Joules, but some Express them in BTU.

In fact, it is like this :δu=M+W, even if the guy in the video is represented as ΔE and δu. Q is the heat, this force or energy that enters the system, W stands for work on the system.

The guy who Uploaded the video on YouTube tells more about the simple basics first law of thermodynamics. It identifies some of the equations and tells us that we should pay attention is to check!
