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.
What happens to the molecular motion when heat energy is increased?
When heat energy is increased, the molecules in a substance gain more kinetic energy and move faster. This increased molecular motion leads to a rise in temperature and can result in changes in the state of matter, such as melting or boiling.
How does adding heat affect molecular motion?
Adding heat increases the kinetic energy of molecules, causing them to move faster and more randomly. This increased molecular motion can lead to changes in the physical state of matter, such as melting a solid into a liquid or vaporizing a liquid into a gas.
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 determines a materials state of matter?
A material's state of matter is determined by the arrangement and movement of its particles at the molecular level. In solids, particles are tightly packed and vibrate in place; in liquids, particles are more spread out and can flow past each other; and in gases, particles are widely spaced and move freely. Temperature and pressure are key factors that can influence the state of matter.
What does the greatest molecular motion occur in?
I would assume in a plasma which is the form which requires the most energy to stay in the same state of matter, and therefore an abundance of molecular movement.
Which state of matter has the least molecular motion?
The solid state has the least molecular motion.
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level

What is the speed at which molecules or atoms move dependent on temperature and state of matter?
The speed at which molecules or atoms move is dependent on temperature and state of matter. In general, higher temperatures result in faster molecular or atomic movement, while different states of matter (solid, liquid, gas) have different average speeds of molecular motion due to differences in intermolecular forces.
In which state of matter is there no particle motion?
Motion just stop at absolute zero.
Which state of matter engages in vigorous motion?
gaseous state.
What are the two main ideas of the kinetic-molecular theory of matter?
The kinetic-molecular theory of matter posits that all matter is composed of tiny particles that are in constant motion. This motion varies depending on the state of matter—solid, liquid, or gas—affecting properties like temperature and pressure. Additionally, it suggests that the energy of these particles influences their behavior, with higher temperatures leading to faster particle movement. Overall, the theory helps explain the physical properties and changes of different states of matter.
Which state of matter has the greatest distance between the individual particles?
Gas is the state of matter with the most space between molecules. The 4th and most abundant state of matter 'Plasma' can be similarly diffuse, mainly as the electrons and protons in space not bound into molecular gas.
What particles that make up matter are in a state of?
Particles that make up matter are in a state of constant motion.
