Water maintains an equal level in connected vessels.
What is this property called?

Water has a high specific capacity. Why can water release a large amount of energy without a great change in temperature?

What causes this color distribution in the knife shown below? A chemical that causes light to change wavelength? A product of the heating process?

When an observer measures a system, the systems wavefunction collapses and they become entangled. Does this mean that any further measurement by the observer on the system is impossible, as the system no longer has a wavefunction that is independent of the observer to collapse?
