Some of the most fundamental concepts of fluid properties are temperature, density, and composition.
Energy flows from high to low.
Answer:

Explanation:
Given that,
Width of a one dimensional potential box, 
The energy of a particle in one dimensional box is given by :

h = Planck's constant
m = the mass of the proton
For minimum kinetic energy, n = 1


So, the minimum kinetic energy of the neutron is
. Hence, this is the required solution.
The correct answer to the question is : D) 352.6 m/s.
CALCULATION :
As per the question, the temperature is increased from 30 degree celsius to 36 degree celsius.
We are asked to calculate the velocity of sound at 36 degree celsius.
Velocity of sound is dependent on temperature. More is the temperature, more is velocity of sound.
The velocity at this temperature is calculated as -
V = 331 + 0.6T m/s
= 331 + 0.6 × 36 m/s
= 331 + 21.6 m/s
= 352.6 m/s.
Here, T denotes the temperature of the surrounding.
Hence, velocity of the sound will be 352.6 m/s.
