It either absorbs or releases an unexpectedly large quantity of energy.
When energy is removed from matter, the matter typically cools down and its particles slow down in movement. This can lead to changes in the physical state of the matter, such as condensation or solidification. However, the matter itself remains the same in terms of its chemical composition.
When matter is heated, its particles gain kinetic energy, causing them to move faster and vibrate more. This increase in energy leads to a rise in temperature and can result in changes in the physical state of the matter, such as melting or boiling. The energy that is added to the matter during heating is stored within the particles as heat energy.
When a substance changes state from a solid to a liquid, it undergoes melting where it gains enough energy to break the bonds holding its particles together. When it changes from a liquid to a gas, it undergoes vaporization where it gains enough energy to overcome the forces of attraction between its particles.
No, matter can undergo physical or chemical changes that alter its original state. Physical changes, like melting or freezing, do not change the chemical composition of the matter, while chemical changes result in the formation of new substances with different properties.
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
It means that although it changes, no new substances are formed. Examples of such changes are melting and other state changes, and dissolving.
Matter changes state because of pressure and temperature.
how temperature can bring about changes in the state of matter
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,
The density changes.
Matter changes state because of temperature and pressure. These quantities bring change.
Changes of state of matter are physical processes, the molecule remain unchanged.
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
gas
the matter can change into liquid, solid and gas.
