Energía interna¶

Fig. 120 The internal energy of a system depends on many variables that define its state. For example, part of the energy of the fuel used up by the car is used to heat up the engine. In a car crash, part of the energy goes into deforming the car not changing the speed of the car.¶

Fig. 121 (a) A system that does not exchange mass or energy is called isolated system. (b) A system that can exchange energy but not mass with its surroundings is called a closed system. (c) A system that can exchange both mass and energy with its surroundings is called an open system.¶
Magnitudes escalares¶
I am writing an equation inline \(x=-i\hbar\psi=\hat{h}\psi\).
If the equation is by itself,
I am going to add a figure

Fig. 122 Here is my figure caption!¶

Magnitudes vectoriales¶
There are many ways to write content in Jupyter Book. This short section covers a few tips for how to do so.
I am going to cite a reference [HdHPK14]
Now I am going to cite section escalares Sec. Magnitudes escalares
The Schrödinger equation is Eq. (195)
I am citing the figure: Fig. 102
