In terms of particles, what is the difference between a liquid and a solid?
A) a liquid has more thermal energy than a solid
B) A solid has more thermal energy than a liquid
C) Both solids and liquids have the same amount of thermal energy
The correct answer is A hope this is right :)
The correct answer is A) a liquid has more thermal energy than a solid.
To understand the difference between a liquid and a solid in terms of particles, we need to consider the behavior of their molecules or atoms.
In a solid, the particles are closely packed together in a regular arrangement and vibrate around fixed positions. These particles have the least amount of kinetic energy and are held together by strong attractive forces, such as intermolecular forces or chemical bonds. As a result, solids have a definite shape and volume.
On the other hand, in a liquid, the particles have more kinetic energy compared to those in a solid. This increased kinetic energy allows the particles to overcome some of the attractive forces holding them together, enabling them to move more freely. While the particles in a liquid are still close together, they can slide past each other, resulting in a fluid-like behavior. Liquids do not have a definite shape, but they have a definite volume.
Thermal energy refers to the kinetic energy associated with the random motion of particles. Since the particles in a liquid have more kinetic energy than those in a solid, a liquid has more thermal energy. This corresponds to the particles in a liquid being in a higher energy state and having greater freedom of movement.
Hence, we can conclude that the difference between a liquid and a solid, in terms of particles, is that a liquid has more thermal energy than a solid.
The question you ask yourself is this?
Energy causes particles to move. How much are particles moving in a liquid vs a solid?
