How do the molecular energy molecular motion and overall mass of a substance change when matter changes state?
When matter changes state, the molecular energy generally increases as heat is added or decreases as heat is removed. Molecular motion increases as the substance transitions from a solid to a liquid to a gas. The overall mass of the substance remains the same throughout the phase change process, as no particles are added or removed.
Does molecular motion decrease when water is boiling?
No, molecular motion actually increases when water is boiling. When water reaches its boiling point, the molecules absorb enough heat energy to break free from the liquid phase and transition into the gaseous phase, leading to increased molecular motion.
What is the liquid phase?
There are three states of matter. they are solid , liquid and gas. A substance is said to be in a phase when it exhibits that state of matter. Ice is water in the solid phase. Water is ice in the liquid phase. Water vapour/steam is water and or ice in the gaseous phase.
What change in state involves a decrease in molecular motion?
The change from a gas to a liquid involves a decrease in molecular motion. In this phase transition, the particles come closer together, reducing their kinetic energy and resulting in a more ordered arrangement.
Which change in state involves a decrease in molecular motion?
The change from a gas to a liquid involves a decrease in molecular motion. In this phase transition, particles lose energy and come closer together, resulting in a decrease in their overall movement and a more ordered arrangement.
What does Molecular Motion mean?
Molecular motion refers to the movement of molecules in a substance, which is manifested through various forms like translation, rotation, and vibration. This motion is driven by factors such as temperature and energy, and it affects the physical properties and behavior of substances. Understanding molecular motion is crucial in fields like chemistry and physics for explaining phenomena like diffusion and phase transitions.
What phases of matter would you most likely to find molecular compounds?
Molecular compounds are most commonly found in the solid and liquid phases of matter. In the solid phase, they typically form crystalline or amorphous structures, while in the liquid phase, they exist as discrete molecules interacting through intermolecular forces. Some molecular compounds can also exist in the gaseous phase under certain temperature and pressure conditions, but they are less stable as gases compared to ionic compounds.
What molecular changes happen when thermal energy is added or removed from nitrogen?
When thermal energy is added to nitrogen, the molecular motion increases, causing the molecules to vibrate and move more rapidly. This results in an increase in temperature. When thermal energy is removed, molecular motion decreases, leading to a decrease in temperature. The phase of nitrogen may change depending on the temperature, transitioning between solid, liquid, and gas states.
