Water changes state depending on its temperature and pressure. When water is heated, it can change from a solid (ice) to a liquid (water) to a gas (steam). When water is cooled, it can go from a gas to a liquid to a solid. These changes in state are due to the energy levels of the water molecules.
The change of water into steam is a physical change. This is because the molecules of water are simply being rearranged into a different state (liquid to gas) without undergoing any chemical reactions.
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
Heating water in a pan is a physical change, not a chemical change. The heat energy causes the water molecules to gain kinetic energy, leading to an increase in temperature and a phase change from liquid to gas (steam). The chemical composition of water remains the same.
No, the process of water being split into hydrogen and oxygen is a chemical change, not a change of state. During this process, new substances are formed through a chemical reaction, rather than a change in the physical state of the water molecules.
Temperature. Temperature causes matter to change state.
They are the same substance, just in a different state. Ex: water>ice>water vapor is still water.
It causes matter to change by turning the water into gas which is vaporization, turning water into ice.
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
decrease in temperature and compact arrangement of its atoms..in the state of ice the water has the least density i-e 0.9168 g/cm3.
heat will change it
The change of state from gas to liquid, also known as condensation, causes cooling to the atmosphere. During condensation, water vapor in the atmosphere releases heat energy as it transforms into liquid water, resulting in a cooling effect.
Light bends or refracts when it goes from water to air because the speed of light is different in the two mediums due to their different densities. This change in speed causes the light to change direction.
It is a physical change because it's still a form of water just a different state.
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
The evaporation of water is an example of a physical change, where water changes from its liquid state to a gaseous state without any change in its chemical composition.
Light bends in water due to a change in speed as it moves from air into water. This change in speed causes the light to change direction, a phenomenon known as refraction. Refraction occurs because light travels at different speeds in different mediums, such as air and water, causing it to bend when it passes from one medium to another.
