Answer: Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.

Answer: The quantity of heat required to raise the temperature of 1 mole of a substance by 1K
Explanation:
As the temperature change is same in all scales of temperature.
The quantity of heat required to raise the temperature of a substance by one degree Celsius or one degree Kelvin or one degree Fahrenheit is called the heat capacity.
The quantity of heat required to raise the temperature of 1 gram of substance by one degree Celsius one degree Kelvin or one degree Fahrenheit is called as specific heat capacity.
The quantity of heat required to raise the temperature of 1 mole of substance by one degree Celsius or one degree Kelvin or one degree Fahrenheit is called as molar heat capacity.
When Ph = -㏒[H+] and when we have [H+] represents by [H3O+]= 9.5x10^-9 M
as the Ph is equal the negative ㏒ of the concentration of H+ ions or H3O+ hydronium ions.
So, by substitution in Ph equation:
∴ Ph = -㏒(9.5x10^-9)
= 8.02
1 lbs --------------- 0,453592 kg
33 lbs -------------- ??
33 x 0.453592 / 1 => 14.9685 kg
Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water.
