Is water is heated and changed to steam is it a physical or chemical change?
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.
Is water heated and changed to steam a physical or chemical change or both?
physical only, you are only changing its state, not its composition.
If water if heated and changed into steam is this a chemical or physical change?
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.
When a tea kettle begins to whistle is this a physical or chemical change?
No. the hissing and steaming is simply the Physical Change of water boiling, and the steam causes an increase in pressure thus the whistle. During a Physical Change, some properties of material change, but the composition of the material does not change.
When water is heated and changed into o steam is that a chemical or physical change?
The change from water to steam is a physical change. It involves a change in the physical state of the substance without any alteration in its chemical composition. The water molecules are still the same, they are just being converted from a liquid to a gas state.
Is heat changing H2o to steam a physical or chemical change?
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply gaining enough energy to break free from their liquid state and form a gas. No new substances are formed in this process.
Why steam condensing is physical change?
Steam condensing is considered a physical change because it involves a change in the state of matter (from gas to liquid) without a change in the chemical composition of the substance. The molecules in the steam lose energy and come closer together to form liquid water, but they remain the same H2O molecules.
Is steam a chemical raection?
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
Is production of steam a chemical or physical change?
The change from liquid water to steam is a physical change in the state of matter. Evaporation is the term for a liquid becoming a gas.
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
When does physical chang happen?
a physical change happens when something is changed physically, for example, snapping a twig or popping a balloon is physical change, but actions like burning wood or cooking an egg are not physical.
