When air is forced into the open pipe,
L =
where n represents any whole number such as 1,2,3,4, etc., and λ denotes the wavelength of the oscillation
This implies λ=
It is important to note that n=1 corresponds to the fundamental frequency, n=2 corresponds to the first harmonic, and so forth.
Thus, the third harmonic will be for n=4
With L=6m and n=4, solving for λ yields:
λ= =3m
The connection between frequency (f), sound speed (c), and wavelength (λ) is given by:
c=f.λ or f=
≈115 Hz
Answer:
The amount of heat that enters the gas throughout this two-step process totals 120 cal.
Explanation:
Given that,
Moles present = 3
Heat capacity at volume held constant = 4.9 cal/mol.K
Heat capacity at pressure held constant = 6.9 cal/mol.K
Starting temperature = 300 K
Ending temperature = 320 K
We are tasked with determining the heat absorbed by the gas at constant pressure
Employing the heat formula
Substituting the values into the equation
Next, we calculate the heat absorbed by the gas at constant volume
Using the corresponding heat formula
Insert the values into the formula
Now, it's necessary to evaluate the total heat flow into the gas during both steps
Using the total heat formula
Thus, the heat that transfers into the gas throughout this two-step process amounts to 120 cal.
