Predict what you need to do do to use boyle’s law on a macroscopic scale
1 answer:
Answer:
Explanation:
Boyle's law states that:
"For an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume".
Mathematically:
where
p is the pressure of the gas
V is the volume of the gas
The important condition in order to verify Boyle's law in an experiment is that the temperature of the gas must remain constant. This means that the temperature of the gas during the experiment must be kept constant. This can be achieved, for example, by placing the apparatus containing your gas (for example, a glass tube) inside a thermal bath: for instance, a large amount of water kept at constant temperature. This way, the gas inside the tube will also have the same temperature of the water, which is constant.

<u>Answer:</u> The wavelength of spectral line is 656 nm
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant =
= Final energy level = 2
= Initial energy level = 3
Putting the values in above equation, we get:
Converting this into nanometers, we use the conversion factor:
So,
Hence, the wavelength of spectral line is 656 nm
