Answer:
844°C
Explanation:
The problem can be easily solve by using Fick's law and the Diffusivity or diffusion coefficient.
We know that Fick's law is given by,
Where is the concentration of gradient
D is the diffusivity coefficient
and J is the flux of atoms.
In the other hand we have, that
Where is the proportionality constant,
R is the gas constant, T the temperature and is the activation energy.
Replacing the value of diffusivity coefficient in Fick's law we have,
Rearrange the equation to get the value of temperature,
We have all the values in our equation.
Substituting,
2.89watts.
<h3>What is meant by sound intensity?</h3>- The average rate at which sound energy moves across a unit area normal to a given direction is used to determine a sound's intensity. This rate is generally stated in ergs per second per square centimeter.
- Decibels are the units used to measure sound intensity, often known as sound power or sound pressure. The decibel (dB) unit is named after Alexander Graham Bell, who also created the audiometer and the telephone. An audiometer is a tool to gauge a person's hearing capacity for various noises.
- Our ability to measure the flow of sound energy as a time-averaged vector quantity makes sound intensity measuring an effective method. We can identify sound sources and tell direct sound from reverberant sound in a room using the characteristics of sound intensity.
How much power is radiated as a sound from a band whose intensity is 1.6x10-3 w/m2 at a distance of 12m:
Formula:
I=1.6x10-3 w/m2
r=12m
