When silver is poured into the mould the it will solidify
In this process the phase of the Silver block will change from liquid to solid.
This phase change will lead to release in heat and this heat is known as latent heat of fusion.
The formula to find the latent heat of fusion is given as
here given that
now we can find the heat released
So it will release total heat of 55.5 kJ when it will solidify
Answer:
The length of the resonating air column is 15 cm.
Explanation:
Given;
fundamental frequency of the air column, F₀ = 550 Hz
Assume speed of sound in air, v = 330 m/s
The wavelength of the air column is calculated as;
The length of the resonating air column is calculated as;
In fundamental mode for closed pipe;
Therefore, the length of the resonating air column is 15 cm.
