Find the rms speed of the molecules of a sample of n2 (diatomic nitrogen) gas at a temperature of 35.9â°c.

The root mean square velocity (RMS velocity) is a method to find a single velocity value for the particles. The average velocity of gas particles in a mixture is found using the root mean square velocity formula:

 μrms = sqrt (3RT/M)

Where,

R = universal gas constant = 8.3145 (kg·m^2/s^2)/K·mol

T = temperature = 35.9 ˚C = 309.05 K

M = molar mass = 28 * 10^-3 kg / mol

Substituting the given values into the equation:

μrms = sqrt [(3 * 8.3145 (kg·m^2/s^2) /K·mol) * (309.05 K) / (28 * 10^-3 kg / mol))]

μrms = sqrt (275,313.8813 m^2)

μrms = 524.7 m / s                     (ANSWER)

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
