Question

The speed of sound in neon gas (A=20, y=1.67) at temperature T is measured to be 451 m/s, determine the value of T.

Answer 1

desired temperature comes out to be equal to 293 K

Step-by-step explanation:

M =20 g/ mol

= 0.02 kg/mol

γ = 1.67

R is (gas constant) = 8.314 J/ mol K

we know that,

`v = \sqrt{(\gamma R T)/(M) }\\ v^2 = {(\gamma R T)/(M)\\`

`451^2 = {(1.67* 8.314 * T)/(0.02)`

`T=293 K`

hence the desired temperature comes out to be equal to 293 K.
