The relationship used to determine the heat energy required to change the state of a substance is: \(E_{h} = ml\) \(E_{h}\) is the energy required to change the state ( \(J\)) \(l\) is the specific ...

THE letter of Dr. J. Newton Friend in NATURE of December 26, 1936, on this subject raises interest in his equation. I have tested it with the following results: As many know, the variation of the ...

I AM grateful to Prof. Satterly for directing attention to the discrepancy. Accepting 5 × 4 = 20 as the molar latent heat of evaporation of helium, the value 31.3 calculated with the aid of the ...
