What type of changes occur when water changes from liquid to solid?
When water changes from liquid to solid, it undergoes a phase change called freezing. During this process, water molecules slow down and come closer together, forming a crystalline structure. This change also leads to a decrease in energy and a release of heat.
How are evaporation and transformation different?
Evaporation is a phase change process in which a liquid turns into a gas at the surface of the liquid, while transformation refers to a change in the structure or composition of a substance, such as in chemical reactions or physical changes. Evaporation typically involves only a change in state, while transformation can involve various changes beyond state, such as chemical composition or physical properties.
What is molecular movement phase changes?
Phase change is when a substance changes it's phase to either a solid, liquid, or gas. Solids have the least molecular movement because the molecules are so tightly bonded that they only vibrate. Liquids have the next fastest molecular movement, because the molecules tend to "flow" over each other. They are still bonded, like solids, but just not as tightly. This is why they move faster. Gases, however, have the fastest molecular movement. The molecules "zip" around and move wherever they want. They are not bonded at all. Hope this helps.
How do the the phase diagrams for water and carbon dioxide differ?
both have a solid, liquid, and gas phase. it's just that to get CO2 in the liquid phase takes a lot of effort and is highly reactive in terms of it quickly evaporates to the preferred state of gaseous CO2.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Explain why a phase changes are a property of an atom?
Because atoms only go through phase changes
How does water changes as it evaporates?
It is only a change of phase, the molecule remain unchanged.
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
How long does take to design a simple website?
There are so many routes for developing a website, different sites having different requirements, I am giving you a brief of them, the life cycle of web design are as follows: Phase 1 - Planning Phase 2 - Analysis Phase 3 - Design Phase 4 - Design Implementation Phase 5 - Testing Phase 6 - Implementation (Public Release) Phase 7 - Maintenance and Changes This is not compulsory that every-time you have to follow this trend only, requirements and planning matters, but the core steps are as above!
Does the moon phase during the night?
No, it only changes during day time when we're incapable of seeing it.
Are melting butter and melting ice cream are both physical change or chemical change?
They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
What kind of terms may be added in an algebraic expression?
Similar terms. These are terms in which the variables have the same power in each term, and only the coefficient changes.
How are the homogeneous different from the heterogeneous?
A homogeneous solution has only one phase.
What are the six different phase changes?
The six different phase changes are: Melting (solid to liquid) Freezing (liquid to solid) Vaporization (liquid to gas) Condensation (gas to liquid) Sublimation (solid to gas) Deposition (gas to solid)
Why do only Greeks name different terms?
greeks always named different terms as they were the most educated at that periiod of time.like what of biology,the greek only knew the word to express the study of living things,so greeks named it,as they had enough education to express it.so,greeks only named different terms.
How many terms do ballet dancers have to know?
lots of different ones. not only English terms, but french aswell. a ballet teacher will usually use only the french terms.
What cannot be considered a single phase?
A heterogeneous mixture, such as a salad with different vegetables, cannot be considered a single phase. It contains distinct regions with different compositions and properties, making it a multi-phase system.
