Answer : Gaseous water molecules condense when they cooled. Liquid water molecules evaporate when they heated.

Explanation :

Condensation : It is a process in which a phase changes from gaseous state to liquid state. This process occurs when the water molecules in the air cool down and they join together to form liquid water.

Evaporation : It is a process in which a phase changes from liquid state to gaseous state. This process occurs when the water is heated, the molecules in the water move and vibrate quickly that they escape into the atmosphere as water vapor.

From each drop-down menu, a solid has (a definite volume and a definite shape), a Liquid has (a definite volume) and gas has ( non of the above)

<h3>The features of different states of Matter:</h3>

Matter is defined as anything that has weight and occupies space.

There are three states of matter that is in existence which include:

  • Solid: The particles of solid are closely packed together and vibrate around fixed axes. That is why they have a definite shape and volume.

  • Liquid: The particles of liquid, though attracted to each other,move freely over each other. That is why they have definite volume but not a definite shape.

Therefore, a liquid occupies the shape of its container.

  • Gas: The particles of gas contain scattered molecules that are dispersed across a given volume.

Therefore, a gas neither has a definite shape nor volume.

Elemental Li and Na are prepared by electrolysis of a molten salt, whereas K, Rb, and Cs are prepared by chemical reduction.(c)
pishuonlain [190]

Calcium is used to isolate Rb from molten RbX because calcium has a smaller atomic radius than rubidium.

A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's core and the outermost isolated electron, serves as a gauge for the size of an atom. There are numerous non-equivalent definitions of atomic radius since the border is not a clearly defined physical entity. Van der Waals radius, ionic radius, metallic radius, and covalent radius are the four most frequently used definitions of atomic radius. Atomic radii are typically measured in a chemically bound condition since it is challenging to isolated individual atoms in order to measure their radii individually.
