A) Water freezing
This is called the process of turning water as a liquid to its solid form which is ice.
Ice is almost together as one unlike liquid. This is why the molecules are more orderly.
The process of freezing is exothermic which means the heat has to be removed in the process.

Is there a more speciific question?
Explanation:
Answer:
The distance at which nose of the vehicle will the shock wave impinge upon the ground is approximately 23km
Explanation:
Let
u be Mach angle
M be Mach Number = 2.5
h be altitude = 10km
d be distance between nose of the vehicle with which the shock wave impinge upon the ground
Using;
Sin u = 1/M
u = arcSin (1/M)
u = arcSin (1/2.5) = 23.58°
Using angle at a point rule = 90°
90 - 23.58 = 66.42°
Tan A = opp/adj
Tan 66.42° = d/10
2.2911 * 10 = d
d = 22.911km ≈ 23km
