Answer:
Explanation:
Given: The latent heat of fusion for Aluminum is
mass to be malted m = 0.75 Kg
Energy require to melt E = mL
Therefore, energy required to melt 0.75 Kg aluminum
<span>This is because Helium
has two valence electrons compared to Hydrogen which has only one. Helium has
more energy levels for an electron to jump thus more spectral lines to occur.
The spectral lines relating to each change of energy level would be more
grouped together and hence the greater chance of them falling in the visible
range.</span>
