How does KMT explain the changes of state?
The Kinetic Molecular Theory (KMT) explains changes of state by describing how the motion and interactions of molecules change as temperature or pressure is altered. For example, when a substance is heated, the molecules gain kinetic energy and move faster, leading to a change from a solid to a liquid or a liquid to a gas. Similarly, increasing pressure can compress gases and cause them to change from a gas to a liquid or solid state.
What are the physical quantities and the manner in which these need to be altered for liquifying gases?
To liquefy gases, key physical quantities such as pressure and temperature must be altered. Increasing the pressure of a gas can lead to liquefaction, as it forces gas molecules closer together. Simultaneously, lowering the temperature reduces the kinetic energy of the molecules, which helps them condense into a liquid state. The combination of high pressure and low temperature is essential for effective gas liquefaction.
When water is warmed what happens to the molecules?
When water is warmed, its molecules gain kinetic energy and start to move more rapidly. This increased movement causes the molecules to spread apart, resulting in a decrease in density. As a result, warmer water tends to rise above cooler water, which can influence circulation patterns in bodies of water. The overall effect is that the physical properties of water, such as viscosity and surface tension, are altered as temperature increases.
Is sucrose dissolving a chemical change?
No, it is a physical change because the molecules of sucrose are not altered, just suspended in a solvent.
What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?
Firstly, momentum is not a form of energy; the question seems to imply so. Kinetic energy is the energy possessed by a moving object. That energy is provided by a source, and can be removed from the object because energy possessed by an object is not an inherent part of that given object. Momentum is a property of mass; momentum is inherent in the mass of the object, and cannot be removed or put somewhere else, only altered.
What is altered when a liquid at its boiling point is converted to a gas at the same temp 1-Size of the molecules 2-Distance between molecules or 3-Kinetic energy of molecules?
II. The distance between the molecules.
When potential energy turns into kinetic do the air molecules expand?
Molecules of air are mainly nitrogen and oxygen, N2 and O2. The '2' subscript means each molecule contains two atoms. The molecules themselves do not change with changes in energy, pressure, temperature etc. I'm not sure what you mean by potential energy turning into kinetic energy. I can visualise one route, where you have air pressurised in a container, then you release the pressure and the air rushes out, gaining kinetic energy. In this case the molecules of air will soon collide with the air that they are going into and be slowed down until mixed and at the same pressure and temperature. The density of the air will be lower than it was in the pressurised container. This means not so many molecules in a unit volume, so their mean distance apart will be greater. If that is what you mean by 'expand' then I agree, but the molecules themselves are not altered.
How can the molecules in one state of matter be converted into another state of matter?
Molecules can change states of matter through the processes of melting, freezing, vaporization, condensation, and sublimation. These changes in state occur when the temperature or pressure of the substance is altered, causing the molecules to rearrange in a way that transitions the substance from one state to another.
Which food molecules are altered in the stomach?
proteins

What happens when the protein shape has been altered?
When a protein's shape is altered, it may lose its functionality. This can disrupt its ability to interact with other molecules and carry out its specific biological functions. The altered protein may also be targeted for degradation by the cell's quality control mechanisms.

Why does it happen enzyme after it participates in a reaction?
After the enzyme has converted the substrate to the product, it is now free to accept more substrate. The enzyme does not get changed or altered in a reaction.
When you rip your notebook is that a physical change?
Yes, ripping your notebook is a physical change because the substance (paper) remains the same, only its shape has been altered. The paper molecules are not chemically altered during the ripping process.
