Which of the following colors is/are produced when white light from sun is passed through a prism?

faust18 [17]

Answer:

Options d.

Explanation:

As white light from the sun is passed through a prism, it is separated into colors - red, violet, yellow, blue, green, orange, and indigo.

Dispersion is the process of the separation of visible light into its different component colors. The light waves are refracted as they enter the prism.

So, option d. is correct.

If 9.9L of helium are in a tire at 303k,how many liters will be present at 403k if the pressure is held constant.

Slav-nsk [51]

Answer:

Final volume, V2 = 13.18 Liters

Explanation:

<u>Given the following data;</u>

Initial volume = 9.9 L

Initial temperature = 303 K

Final temperature = 403 K

To find the final volume, we would use Charles law;

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles' law is given by the formula;

$VT = K$

$\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$

Where;

V1 and V2 represents the initial and final volumes respectively.
T1 and T2 represents the initial and final temperatures respectively.

$\frac{V1}{T1} = \frac{V2}{T2}$

Making V2 as the subject formula, we have;

$V_{2}= \frac{V1}{T1} * T_{2}$

$V_{2}= \frac{9.9}{303} * 403$

$V_{2}= 0.0327 * 403$

<em>Final volume, V2 = 13.18 Liters</em>

Suggest 2 reasons why the noble gases become less ideal in their behaviour down the group from helium to xenon.

Elenna [48]

Reason1: electrons on farther layers become free easyer
2nd reason: volume of atoms grows (from Helium to Xeon) so instead of boyle-mariot law equation (PV=vRT) is more accurate to use van der walls equations that adds to the boyle-mariot equation the volume occupied by the atoms of the gas to the volume of the space between the atoms P(Vm-b)=vRT
