Answer 1

Explanation:

Explain the different types of frictional forces with examples?

Answer 2

Speed of sound in hydrogen gas = 59.09 m/s

Given:

Hydrogen gas at 27° .

Ratio $C_p/C_V$ = 1.4  

Gas constant R =8.31 J//mol -K.

To find:

Speed of sound in hydrogen gas.

Formula used:

Speed of sound = $\sqrt{\frac{\gamma R T}{M} }$

Where M = molecular mass of gas.

Explanation:

We know that molecular mass of hydrogen gas =1

Temperature = T = 27°  = 273 +27 = 300 k

Speed of sound in hydrogen gas = $\sqrt{\frac{\gamma R T}{M} }$

Speed of sound in hydrogen gas = $\sqrt{\frac{1.4\times 8.314\times 300}{1} }$

Speed of sound in hydrogen gas = 59.09 m/s
