Recently you viewed a movie in which a spaceship blows up outside a space station. The people inside the space station jump with

surprise upon hearing the explosion. What is wrong with this scenario? Sound is a transverse wave. Sound needs a medium through which to travel. Sound is a longitudinal wave. There are no such things as space stations. NEXT

Answer:

Sound needs a medium through which to travel.

Explanation:

In space there is no air or medium. Sound waves  need medium to travel. It cannot travel through vacuum. Sounds waves are mechanical waves unlike electromagnetic waves. Electromagnetic waves can travel through vacuum. But mechanical waves such as sound waves needs a medium to propagate the energy. So it is very unlikely that people inside the space station can hear the explosion that occurs in space outside the space station.

Consider the reaction. At equilibrium, the concentrations are as follows. [NOCl] = 1.4 ´ 10–2 M [NO] = 1.2 ´ 10–3 M [Cl2] = 2.2
EastWind [94]
2NOCl ⇄ 2NO + Cl₂

K = [NO]²[Cl₂]/[NOCl]
K = [0,0012]²[0,0022]/[0,014]²
K = 0,000000003/0,000196
K = 0,000016163
