Mass cannot be created or destroyed, and will therefore remain constant even when matter changes its state. The volume, on the other hand, can change because volume is a state function (dependent on the state of the system). Mass is an intrinsic property of the system.
Weight and mass are commonly used interchangeably but are actually two different concepts. Weight is the gravitational force acting on a body defined as W=mg, where g is the gravitational constant. On earth, g = 9.81 m/s2, and the correct unit of weight is the Newton. Weight also remains constant with state changes.
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Yes, changes in state of matter involve physical changes because the substance retains its chemical composition. The change is simply a rearrangement of particles due to differences in energy levels or intermolecular forces, rather than a chemical reaction.
The most common reason for matter changing its state is a change in temperature. When heat is added or removed, the energy in the particles of matter changes, causing them to rearrange and transition from one state to another (e.g. solid to liquid, liquid to gas). This change in energy alters the intermolecular forces between particles, leading to a change in state.
Plasma is a state of matter that does not have its own volume or shape. Plasma is a hot, ionized gas where the electrons are separated from the atoms, resulting in a mixture of positively charged ions and free electrons.
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.
Gases adapt most easily to changes in volume.
Liquid
gas
True. A physical change occurs when matter changes state without altering its chemical composition. In this case, the change from a liquid to a gas involves only changes in physical properties such as volume, shape, and density.
Gas.
Gas
no physical change does not change matter
A liquid.
When matter changes its state, its physical properties such as density, shape, and volume also change. This change in state usually involves the absorption or release of energy. The three common states of matter are solid, liquid, and gas, and transitions between these states involve changes in the arrangement and movement of particles.
the matter can change into liquid, solid and gas.
With the help of some physical and chemical processes matter changes its state. Like using heating , cooling etc we can change the state of matter,
