Why changes of stat are physical changes?
Changes in state are physical changes because they involve a change in the physical appearance or state of a substance without altering its chemical composition. For example, when water changes from a liquid to a solid (freezing) or a gas (vaporization), it is still water chemically. This contrasts with chemical changes, which involve a rearrangement of atoms and result in the formation of new substances.
How are all physical changes alike?
All physical changes involve a change in the form, shape, or state of matter without altering the chemical composition of the substance. This means that the particles in the substance remain the same before and after the change, only their arrangement or state is altered.
Can an object undergo both physical and chemical changes?
Yes, an object can undergo both physical and chemical changes. Physical changes involve changes in physical properties like shape, size, or state of matter without altering the composition. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances.
How are physical and chemical changes distinguished?
Physical changes involve a change in appearance or state of matter without altering the composition, like melting ice. Chemical changes, on the other hand, result in the formation of new substances with different properties, such as rusting of iron. The key difference is that chemical changes involve breaking and forming of chemical bonds.
Can chemical change and physical change happen simultaneously?
No, chemical changes and physical changes are distinct processes that occur separately in a system. Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the state or appearance of a substance without changing its chemical composition. These processes do not typically occur simultaneously.
Do all changes involve physical interaction?
no they don't
Which of the phase changes does not involve changing a liquid into a gas?
All the rest of them.
All changes in a phase are what?
the phases can be changed from a liquid, gas, or solid
Do physical changes involve change in energy?
Yes, physical changes involve a small change in energy.
What are characteristics do all chemical changes have?
All chemical changes involve the formation of new substances with different properties. They typically involve changes in the arrangement of atoms and the breaking and forming of chemical bonds. Chemical changes are often irreversible and are accompanied by changes in energy.
What are the effects of changes in matter?
Changes in matter can lead to physical or chemical changes. Physical changes involve alterations in state or appearance, such as melting or crushing. Chemical changes involve the formation of new substances through reactions, like rusting or burning. Both types of changes can impact properties like color, texture, or composition.
What do Civil Military Operations involve?

What are three key points to interaction perspective?
One key point to interaction perspective is that the different people involved in the interactions will all have different perspectives. Another point to remember is that the perspectives are usually dependent on the backgrounds and experiences of the individuals involve. The third point to keep in mind is that through the interaction itself, the perspectives will be altered.
What is the Interaction of two or more chemicals called?
The interaction of two or more chemicals is called a chemical reaction. During a chemical reaction, reactants undergo a transformation to form products, which may involve the breaking and forming of chemical bonds. These interactions can result in changes in physical properties, energy release or absorption, and the formation of new substances.
