Answer:
The formula defining the photon energies that would be emitted by transitions between the hydrogen energy levels are given by the equation:
ΔE = -13.6Z²[1/n₁² - 1/n₂²]eV, where (1 eV = 1.602×10-19 Joules) and n₁ = initial energy level and n₂ = final energy level.
Z = Atomic number of the atom

Explanation:
The cold drink chiller is a cold substance which is inserted into a bottle of drink which contains warm liquid particles at a particular temperature.
Once the drink chiller is inserted, the liquid molecules around the drink chiller become cooler, denser and sink away from the drink chiller. Other warmer, less dense molecules of the liquid drink now replaces them around the drink chiller.
A convection current is thus set up for as long as the drink chiller is working.
Answer: A
Explanation: the only way to turn it from blue to yellow is to mix it with an acidic solution.
Answer:Yes yes it can
Explanation:Why ? Because Stony Brook University in New York found that CFL bulbs produce incredibly high levels of UVA and UVC emissions, which are harmful to human skin.
