Describe what happens to the particles of a liquid, in terms of movement and kinetic energy, as it is cooled to its freezing poi
nataly862011 [7]
As a system is cooled to its freezing point, the kinetic energy of the particles in the system will lower so the movement are much slower. Cooling means taking out heat from the system. This process is a physical change because it is only the phase of the system is changed and it is still the substance after the process.

What happens when light rays pass through a concave lens?
Alexxx [7]

Answer:

Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.
