Answer:
violet
Explanation:
Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy (google)

Answer:
P₂ = 647 torr
Explanation:
Given data:
Initial pressure = 565 torr
Initial temperature = 27°C
Final temperature = 71°C
Final pressure = ?
Solution:
Initial temperature = 27°C (27+273 = 300 K)
Final temperature = 71°C (71+273 = 344 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
565 torr / 300K = P₂/344 K
P₂ = 565 torr × 344 K / 300 K
P₂ = 194360 torr. K /293 K
P₂ = 647 torr
Iron, nickel, cobalt? I’m not really sure. Hope this helped a little bit.
