When enough energy is supplied, the rigid pattern of molecules is disrupted in a phase change, causing the molecules to move more freely. This disrupts the orderly arrangement of the particles and changes the physical state of the substance.
Yes, during a physical change, molecules remain the same. The arrangement and motion of molecules may change, but the actual atoms that make up the molecules do not change.
When water changes to ice, the arrangement of water molecules changes from a more randomly structured liquid form to a more orderly crystalline form. The atoms themselves do not change in terms of their chemical composition, but their arrangement and movement are altered to form the solid structure of ice.
When a solid melts to become liquid, or a liquid boils to become a gas, the arrangement of particles gets farther apart and less structured, and the motion of the molecules becomes more random and they move faster. The opposite happens when a gas condenses to become a liquid, or when a liquid freezes to become a solid.
No, it is not possible.
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
A change of state can affect a material's texture because it alters the arrangement of molecules within the material. For example, when water freezes into ice, its texture changes from liquid to solid, indicating a change in the arrangement of molecules. Similarly, when a metal material is heated and undergoes melting, its texture changes as well.
When molecules in a substance lose energy and can no longer slide past each other easily, they typically undergo a phase change from a liquid to a solid, known as freezing or solidification. During this process, the molecules slow down and arrange themselves into a more rigid, orderly structure. As energy is removed, the attractive forces between the molecules become stronger, leading to a solid state where the molecules are fixed in place.
During a phase change, the arrangement of molecules changes while their size remains the same. For example, when a solid transitions to a liquid, the molecules rearrange into a more disordered state, but their actual size does not change.
When heat is added, the arrangement of the particle (the Entropy of the system) will become more disorganized and Entropy will increase. When heat is taken away, the arrangement of the particles will become more organized and Entropy will decrease.
