Question

The state of matter in which particles have the least energy is called the __________ state. What word completes the sentence?

Answer 1

Answer:

gaseous state

is the apt word

Answer 2

The state of matter in which particles have the least energy is called the Solid State.

• The Matter in the universe exists in four states majorly as Solid, Liquid, Gas and Plasma.
• Certain Intermediate states are also known to be discovered, but they exist only in extreme conditions. eg. Bose-Einstein condensates, Liquid crystal etc.
• The Solid State has the least energy whereas the gaseous state has the maximum kinetic energy.
• The molecules of the solids are orderly packed in a definite space with little movement. The atoms may have a small vibration because of the continuous motion of the electrons but they are fixed in their position. Therefore it has the lowest entropy. Solids have a definite shape and volume with high density.
• In a  gaseous state, particles have a large space between them and are loosely packed with a great deal of kinetic energy.
