Question
The temperature inside a supernova explosion is said to be $2.00 \times 10^{13} \mathrm{K} .$ (a) What would the average velocity $v_{\mathrm{rms}}$ of hydrogen atoms be? (b) What is unreasonable about this velocity? (c) Which premise or assumption is responsible?
Step 1
Step 1: The root mean square speed $v_{\mathrm{rms}}$ is given by the formula $v_{\mathrm{rms}} = \sqrt{\frac{3kT}{m}}$, where $k$ is the Boltzmann constant, $T$ is the absolute temperature, and $m$ is the molar mass of the gas. Show more…

Unreasonable Results The temperature inside a supernova explosion is said to be $2.00 \times 10^{13} \mathrm{K} .$ (a) What would the average velocity $v_{\mathrm{rms}}$ of hydrogen atoms be? (b) What is unreasonable about this velocity? (c) Which premise or assumption is responsible?
To what temperature should the hydrogen at room temperature $\left(27^{\circ} \mathrm{C}\right)$ be heated at constant pressure so that the rms velocity of its molecule becomes double of its previous value (A) $927^{\circ} \mathrm{C}$ (B) $600^{\circ} \mathrm{C}$ (C) $108^{\circ} \mathrm{C}$ (D) $1200^{\circ} \mathrm{C}$
What are (a) the average kinetic energy and (b) the rms speed of a proton in the center of the sun, where the temperature is $2.0 \times 10^{7} \mathrm{K} ?$
