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.
What form of motion involves a change in an objects position?
Translational motion involves a change in an object's position in space, typically along a straight line or a curved path. This type of motion involves the object moving from one location to another.
Acceleration involves a change in what?
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
What is a change in an object's motion called?
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
What are two characteristics of motion?
Motion involves a change in position of an object over time. It can be described by its speed and direction.

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 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.
Acceleration involves a change in what?
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
What 3 kinds of change motion are called acceleration?
1). increase of speed 2). decrease of speed 3). change of direction of motion
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level
What is a change in an object's motion called?
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
What situations would cause the greatest decrease in the motion of molecules in a system?
The greatest decrease in the motion of molecules in a system would occur at absolute zero temperature, where molecules would have minimal thermal energy and nearly no motion. Another situation that could greatly decrease molecular motion is a high-pressure environment, where molecules are more closely packed together and have less space to move around. Additionally, extremely low energy environments, such as in deep space or at the center of a black hole, would also cause a significant decrease in molecular motion.
What are two characteristics of motion?
Motion involves a change in position of an object over time. It can be described by its speed and direction.
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.
