Se cree que la temperatura cerca del centro del Sol es de 15 millones de grados Celsius $\left(1,5 \times 10^7{ }^{\circ} \mathrm{C}\right)$ (o kelvin). ¿A través de qué voltaje se debe acelerar un ion con carga única para que tenga la misma energía que la energía cinética media de los iones a esta temperatura?

Key Concepts

Boltzmann Constant

This constant (approximately 1.38×10^-23 J/K) is essential in linking the microscopic kinetic energy of particles to the macroscopic temperature of a system. It provides the proportionality between the average kinetic energy of particles and the temperature in kelvin, forming the basis for thermal energy calculations in physics.

Thermal Energy and Average Kinetic Energy

Under the principle of equipartition of energy, the temperature of a system determines the average kinetic energy of its constituent particles. For instance, the average kinetic energy per particle in an ideal gas is proportional to the temperature, which helps in estimating energy scales in high-temperature environments like the core of the Sun.

Electron Volt (eV) as an Energy Unit

The electron volt is a convenient energy unit in atomic and nuclear physics, defined as the energy gained by an electron when it is accelerated through an electric potential difference of one volt. It provides an intuitive scale for comparing energies at the microscopic level, such as those encountered in ion acceleration.

Voltage Acceleration of Charged Particles

The relationship between voltage and energy for a charged particle is given by the fact that a particle with a single elementary charge gains energy equal to the product of the charge and the applied voltage. This concept allows one to determine the necessary voltage to impart a kinetic energy to an ion that matches the average thermal energy at a given temperature.
