Capable of being reversed or of reversing: as a : capable of going through a series of actions (as changes) either backward or forward
Example : water ----> ice

The answer is "matter is made up of tiny particles called atoms"
I believe the correct answer from the choices listed above is the second option It is during sublimation that molecules directly move from state to state involving a vibration of particles in a fixed position to a state involving random movement of high speed particles. It <span> is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. </span>
911.1×155.9 = 14,202.49
14,202.49 in 3 significant figures would be either 14,200 or 1.42×10^4
Answer:
A. potassium
Explanation:
Potassium is expected to have the greater atomic radius from the given choices of element.
Atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid states of metals.
- Across a period, the atomic radii decreases progressively from left to right.
- This is due to the progressive increase in the nuclear charge without increase in the number of electronic shells.
