The specific latent heat of ice or water can be measured using a low-voltage heater connected to a joulemeter to melt the ice or boil the water. These complex molecules are typically made up of chains and rings that contain hydrogen, oxygen, and nitrogen atoms, as well as carbon atoms. Because mass spectrometry measures the mass of charged particles, only ions will be detected, and neutral molecules will not be seen. Nucleic acids, and DNA in particular, are key macromolecules for the continuity of life. Eventually, you get ice particles inside a thick, sugar-rich, syrup-like liquid which does not freeze, that also contains small air bubbles and drops of fat.
