How do you distinguish between heat and mechanical effects?
Heat effects involve the transfer of thermal energy leading to changes in temperature, while mechanical effects involve the application of forces leading to changes in shape or movement of objects. Heat effects typically result in temperature changes without physical displacement, while mechanical effects involve physical displacement or deformation of objects due to the application of forces.
All changes in a phase are what?
the phases can be changed from a liquid, gas, or solid
What are things that have physical changes?
Water because It is first solid its ice then when it melts it is liquid and when it is a gas its water vapor.
What is a list of physical changes?
Examples of physical changes include melting of ice, boiling of water, cutting a piece of paper, breaking a glass, and dissolving salt in water. These changes alter the form or appearance of a substance without changing its chemical composition.
What Logical data independence and physical data?
Logical data independence refers to the ability to modify the conceptual schema without changing the external schemas or application programs. In contrast, physical data independence allows changes to the internal schema – like indexes and storage structures – without affecting the conceptual or external schemas.
Can a chemical changes be reversed by physical changes?
Technically no..... however; the application of "extreme" physical forces can cause chemical change such as applying exiremely high pressure to coal to cause the formation of diamond.
Practical application of physical and chemical change in homescommunity and industry?
Physical changes are commonly utilized in homes for tasks like melting ice, cutting paper, and boiling water. In industry, physical changes are employed in processes such as distillation and filtration to separate mixtures. Chemical changes find application in homes through cooking, cleaning, and corrosion processes. In industry, chemical changes are crucial in manufacturing processes like fermentation, combustion, and polymerization.
What are the two classifications for the changes that matter undergoes?
Physical changeschemical changesYou must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
Are state changes chemical or physical changes?
Physical Changes

Why are chemical and physical changes bad?
they're not bad, its the application you give to what you do, if you make a cake, you are chemical transforming flour into bread, if you make orange juice, you are physical transforming the orange into juice.
What is marijuana physical changes?
what is marijuana physical changes
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Ammonia is used for what commercial application?
Cleaning
