The correct answer is D. Copernicus.
Nicolaus Copernicus completed his education in the university of Krakow of Mathematics. He also studied the stars and planets and didn't believe that the earth was the centre of the universe. Copernicus presented his ideas in a book called ON THE REVOLUTION OF CELESTIAL SPHERES. The book wasn't published for 30 years 'cause the Roman Catholic Church opposed it!

The lowest possible temperature in outer space is 3.13 K. What is the rms speed of hydrogen molecules at this temperature? (The

Umnica [9.8K]

Answer:

$v_{rms} =196.59 m/s$

Given:

Temperature, T = 3.13 K

molar mass of molecular hydrogen, m = 2.02 g/mol = $2.02\times 10^{-3}kg/mol$

Solution:

To calculate the root mean squarer or rms speed of hydrogen molecule, we use the given formula:

$v_{rms} = \sqrt{\frac{3TR}{m}}$

where

R = rydberg's constant = 8.314 J/mol-K

Putting the values in the above formula:

$v_{rms} = \sqrt{\frac{3\times 3.13\times 8.314}{2.02\times 10^{-3}}}$

$v_{rms} =196.59 m/s$
