4. Particles in a gas possess
[least/ very large) kinetic energy
Answers
Answer:
Explanation:
Key Points
All particles have energy, and the energy varies depending on the temperature the sample of matter is in, which determines if the substance is a solid, liquid, or gas. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy.
The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed.
There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.
Key Terms
kinetic molecular theory: Theory of treating samples of matter as a large number of small particles (atoms or molecules), all of which are in constant, random motion
kinetic: Of or relating to motion.
lattice: A regular spacing or arrangement of atoms/molecules within a crystal.
phase: A component in a material system that is distinguished by chemical composition and/or physical state. Matter can exist in the solid, liquid, and gaseous phases.
Answer:
Particles in a gas possess very large potential energy.
Explanation:
The particles of a gas have the least cohesion which enables them to move freely due to which they have the largest kinetic energy as compared to other states of matter.
