Question
The temperature inside a supernova explosion is said to be $2.00 \times 10^{13} \textrm{ K}$. (a) What would the average velocity $v_{rms}$ of hydrogen atoms be? (b) What is unreasonable about this velocity? (c) Which premise or assumption is responsible?
1. $7.03 \times 10^8 \textrm{ m/s}$
2. The speed exceeds the speed of light. This is not possible.
3. The ideal gas law doesn't apply at such high temperatures and pressures.
