What is true about kinetic energy and the mobility of solid, liquid, and gas particles?
The average kinetic energy of the particles decreases as the particles go from a liquid state to a gas state because gas particles do not interact with each other.
The average kinetic energy of the particles increases as the particles go from a solid state to a gas state because gases are more mobile and have more energy.
The average kinetic energy of the particles decreases as the particles go from a solid state to a gas state because gases have lower density than solids.
The average kinetic energy of the particles increases as the particles go from a gas state to a liquid state because liquids have higher energy.
I think its c
Omg someone please please help I’m already behind on this lesson please help!!!!
The correct answer is c. The average kinetic energy of the particles decreases as the particles go from a solid state to a gas state because gases have lower density than solids. In a solid state, the particles are closely packed and have less freedom to move, resulting in lower kinetic energy. As the particles transition to a gas state, they become more mobile and have more freedom to move, which increases their kinetic energy. Gases have a lower density compared to solids, meaning the particles are more spread out and have higher average kinetic energy.
The correct answer is actually b: "The average kinetic energy of the particles increases as the particles go from a solid state to a gas state because gases are more mobile and have more energy."
To understand why this is true, we need to look at the kinetic theory of matter. According to this theory, the particles in a substance are constantly in motion and their kinetic energy is related to their temperature. In other words, the higher the temperature, the higher the average kinetic energy of the particles.
In a solid, the particles are tightly packed and have relatively low kinetic energy. They vibrate in fixed positions, but their movement is restricted due to the strong intermolecular forces holding them together.
In a liquid, the particles have more freedom of movement compared to a solid. They can slide past each other while still being in close proximity. Therefore, the average kinetic energy of the particles in a liquid is higher than in a solid.
In a gas, the particles are not only free to move within the substance but also have sufficient energy to overcome the intermolecular forces entirely. They move randomly and independently, colliding with each other and with the walls of their container. As a result, gas particles have the highest average kinetic energy among the three states of matter.
So, as the particles transition from a solid to a gas state, their average kinetic energy increases because they become more mobile and have greater energy.
