Answer:
What that means is that when pressure and number of moles are kept constant, increasing the temperature will result in an increase in volume. Likewise, a decrease in temperature will result in a decrease in volume. In your case, the volume of the gas decreased by a factor of about 3, from "140.0 mL" to "50.0 mL".

Answer : The wavelength of yellow light produced by a sodium lamp is, 
Explanation : Given,
Frequency of radiation = 
conversion used : 
Formula used :
where,
= frequency of radiation
= wavelength of radiation
c = speed of light = 
Now put all the given values in the above formula, we get:
Therefore, the wavelength of yellow light produced by a sodium lamp is,
