Does an individual atom of helium have a melting point and why or why not? Yes, the melting point of an individual atom can be measured using advanced techniques such as atomic force microscopy. No. an individual atom is too small to see so we cannot measure the temperature at which it changes from a solid to a liquid. Yes, the melting point of helium is the same whether there is one atom or one mole of atoms. No. an individual atom cannot be considered a solid or a liquid so there is no temperature at which it can change from one to the other.

In our previous discussions, we discussed how phase changes (gas to liquid to solid, for example) can occur by manipulating the parameter of temperature. We defined temperature as the average kinetic energy of the particles, so when we raise or lower the temperature, we are adding or removing energy to the system, respectively. Gas Cool or compress Heat or reduce pressure Liquid Cool Heat Crystalline solid Based on your observations over the past two weeks, please explain why lowering the temperature can condense the helium gas into a liquid, a process by which the He atoms stick together?
