The cooling curve above shows how the temperature of a sample varies with time as the sample goes through phase changes. the sample starts as a gas, and heat is removed at a constant rate. at which time does the sample contain the most liquid?

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

The answer should be vaporization
