Explanation:

A substance melting is a physical change and the properties of the substance will remain same, only that the substance will just become liquid.

On the other hand, burning is a chemical change which produces an entirely new compount(in most cases, ash) which does not have the same properties as the original object

¿Qué hecho indujo a Heisenberg a establecer el principio de incertidumbre?
yaroslaw [1]

Answer:

Here's what I find  

Explanation:

Heisenberg observed that if we want to locate a moving electron, we must bounce photons off it.

However, this makes it recoil. By the time the photon returns to our eye, the electron will no longer be in the same place.

He concluded that there is a limit to the precision with which we can simultaneously measure the position and speed (momentum) of a particle.

The more precisely we know the electron's speed, the less precisely we know its position and vice versa.

The uncertainty in the product of the two values cannot be less than a fixed small number.
