Sublimation occurs more readily when definite weather circumstances are present such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes where the air pressure is less than at lower altitudes and energy such as strong sunlight is also needed. Sublimation happens a lot in the south face of Mt. Everest which have low temperatures, strong winds, intense sunlight, very low air pressure and the recipe for sublimation to occur.
"As we move through the visible spectrum of violet, blue, green, yellow, orange and red, the wavelengths become longer. The range of wavelengths (400 - 700 nm) of visible light is centrally located in the electromagnetic spectrum (Fig. 1)."

Answer:
Colors are seen by burning of metal salts, for example Sodium chloride makes yellow frame.
It is very common for fireworks to contain Aluminum, Iron, Steal, Zinc or the Magnesium’s dust to create bright light.
Answer:
The final volume when pressure is changed is 126.1mL
Explanation:
Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:
P₁V₁ = P₂V₂
<em>Where P is pressure and V volume of 1, intial state and 2, final state.</em>

Computing the values of the problem:
350mmHg*200mL = 555mmHgV₂
126.1mmHg = V₂
<h3>The final volume when pressure is changed is 126.1mL</h3>
