Examples: volume, density, thermal conductivity, hardness, compressibility etc.
Changes of state are 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.
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.
The transition from solid to liquid is a state change. Its ability to flow changes.
Well it is in some cases, for exampleMelting of iceIt is a physical and a chemical changeBUT, some physical changes likeCutting of fruitsIt is a physical and irreversible change-----------------------------------------------------------------------------------------------------SO my answer would be (as I said earlier) in some cases
A good example of physical changes is when a quantity of H2O - the compound of chemical elements commonly known as water - is heated, it changes from ice (which is a solid) to water (which is a fluid) to water vapour or steam which is in the form of a gas.
Heat
water into ice water into steam both above are the physical changes physical changes means reversable change which can be brought into its original state eg:steam can be converted into water by cooling and ice into water upopn heating............ its true try it............
Physical, as it remains water.
Changes of state are physical changes.
It changes from a solid to a liquid.
No it is the temperature at which water changes physical state from a liquid to a solid.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
Water because It is first solid its ice then when it melts it is liquid and when it is a gas its water vapor.
Water quantity refers to the amount of water available, while water quality refers to the physical, chemical, and biological characteristics of water. Water quantity focuses on the availability and distribution of water resources, while water quality focuses on the suitability of water for specific uses and its health impacts. Both quantity and quality are important aspects of managing water resources sustainably.
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.
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.
