Is water evaporating from a lake a physical or chemical change?
Evaporation of water from a lake is a physicalchange.They are still water molecules whether in the state of liquid, solid or gas. There has been no chemical change.
Is evaporating of water in a lake a chemical or physical change?
The evaporation of water in a lake is a physical change. This is because the water is changing state from liquid to gas without any change in its chemical composition.
Is evaporating water a physical change or a chemical change?
When water evaporates, it is a physical change.You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is water evaporating from a pond a chemical change?
it is a physical change since water and water vapor has the same chemical composition which is H2O. there is only a change in phase from liquid to gas. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is liquid evaporating a chemical or physical change?
physical change, its molecules are gaining energy and evaporating
Water evaporating from a puddle is a example of a?
Water evaporating from a puddle is an example of a physical change, specifically the transformation of liquid water into water vapor. This process involves a change in state from liquid to gas without altering the chemical composition of the water molecules.
Is water evaporating a chemical change?
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
Is water evaporating into steam chemical or physical change?
It's a physical change because no new substances are formed, the molecules simply get further apart.
IS water evaporating from a puddle a physical or chemical change?
Water evaporating from a puddle is a physical change. During evaporation, water changes from a liquid to a gas, but its chemical composition (H₂O) remains the same. This process is reversible, as the water vapor can condense back into liquid water. Therefore, it exemplifies a change in state rather than a change in chemical identity.
Is sweat evaporating from your forehead a chemical change?
No, sweat evaporating from your forehead is a physical change, not a chemical change. The sweat is merely changing from a liquid state to a gas state without any change in its chemical composition.
Is evaporating alcohol a chemical change?
No. It is a physical change as the actual compound does not change, only its state does.
Is evaporation a chemical or physical change?
While boiling isn't the same as evaporation in that the entire liquid is heated to the point of steam and not just the surface molecules, the same physical change that causes evaporation can be seen in boiling. When boiled, a liquid becomes hot enough that it converts from that form into a gas, and if gathered and cooled, that gas reverts to its liquid form. For example, if a pot of boiling water is covered to trap the steam, that steam gathers on the inside of the cover where it again becomes water. This not the result of any chemical change in the water, just a change in its physical form.SO, EVAPORATION IS A PHYSICAL CHANGE.
