Question

**Question:** Why do atoms in state A experience greater motion compared to atoms in state B?

**Answer choices:**
A) The longer the liquid was heated, the higher the temperature increased.
B) The pH values are ranging from 1 to 13. The colour of the universal indicator changes from red for the most acidic solution (pH = 1) to violet for the most basic solution (pH = 13).
C) The solution would turn red.
D) Due to A being a gas and B being a solid, the atoms within A will experience greater motion in comparison to those within B.

Answer 1

The correct answer is:

D) Due to A being a gas and B being a solid, the atoms within A will experience greater motion in comparison to those within B.

In general, gas particles have more kinetic energy and greater freedom of movement compared to particles in solids, which are more closely packed and have limited motion.
