Integrated Concepts
The temperature near the center of the Sun is thought to be 15 million degrees Celsius $\left(1.5 \times 10^{7} \mathrm{C}\right) .$ Through what voltage must a singly charged ion be accelerated to have the same energy as the average kinetic energy of ions at this temperature?

Key Concepts

Boltzmann Constant

The Boltzmann constant is a fundamental physical constant that relates the average kinetic energy of particles in a system to the temperature of that system. It is a key element in the expression for thermal energy (E = kT), where k is Boltzmann's constant and T is the temperature in Kelvin, and it plays a central role in converting thermal energy into other energy units.

Thermal Kinetic Energy

Thermal kinetic energy refers to the average energy that individual particles of a substance have due to their random thermal motion at a given temperature. This concept is essential in understanding the microscopic behavior of particles in thermodynamic systems, as it forms the basis for calculations involving temperature and energy.

Electron Volt (eV)

An electron volt is a unit of energy defined as the energy gained by a single electron when it is accelerated through an electric potential difference of one volt. This unit is particularly useful in atomic and particle physics as it provides a practical scale to compare the energies involved in atomic and subatomic processes.

Voltage Acceleration of Charged Particles

This concept relates to the process of accelerating charged particles, such as ions, through an electric potential difference. For a singly charged ion, the energy gained (in electron volts) directly corresponds to the voltage applied (in volts). This relationship allows for the direct comparison between kinetic energy acquired through thermal processes and energy imparted through voltage acceleration.
