Why are liquid Hydrogen and liquid Oxygen so cold compared to Water, which is made of the two

we can put the elements Na and Cl into our water to gargle with salt water. Or we can season the stew were cooking.But try putting the individual elements, sodium and chlorine, one at a time, in that water.......

Bill is right. The one I like is ordinary table salt, NaCl.

As table salt, we can put the elements Na and Cl into our water to gargle with salt water. Or we can season the stew we're cooking. But try putting the individual elements, sodium and chlorine, one at a time, in that water. Totally different physical results.

The sodium will burst into flame upon contact with the water. And the chlorine would poison the water so it's undrinkable. Wouldn't want to gargle or season my food with either of these in the water by themselves.

How these things behave is the subject of a very interesting course called physical chemistry. If you're into physics, this is a must course.

Constituents of a compound are always totally different from the compound itself.

Chemical and physical properties are from a variety of things, like number of orbital electrons in outer shell, size of molecule, spins, and much else. And these mostly all change between the constituents and the compound.

This is true for all compounds.
