Is it a physical change chemical change when salt dissolves in water?
Physical
Is salt water drying up a physical or chemical change?
The evaporation of salt water is a physical change because it does not alter the chemical composition of the water or salt. The water is simply changing from a liquid to a gas, leaving the salt behind.
Is water evaporating off the counter a physical or chemical change?
Evaporation is a physical change.
Which process represents a chemical change...Melting of ice OR Evaporation of water?
The process that represents a chemical change is the evaporation of water. This is because the bonds between the H and O atoms in water molecules are broken during evaporation, leading to a change in the substance's chemical composition. The melting of ice, on the other hand, is a physical change where the state of water changes from solid to liquid without altering its chemical structure.
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 evaporation a chemical change?
No, evaporation is a change from liquid to gas (water vapour).
Is removing salt from water by evaporation a physical or a chemical change?
Evaporation is a physical change.
Is water evaporating into steam a chemical or physical change?
It is a physical change because the change is reversible.
Is evaporation of water in a lake a physical or chemical change?
This is a physical change.
Is evaporation of water from a lake a chemical reaction?
No, evaporation of water from a lake is a physical process, not a chemical reaction. It involves the transformation of water from a liquid to a gas without any change in the chemical composition of water molecules.
Is evaporation of water from a cup of water a physical or chemical change?
physical
Is sunlight speeding up the evaporation of a bowl of water a chemical change?
No, sunlight speeding up the evaporation of water is not a chemical change. It is a physical process where the water molecules transition from liquid to vapor state without any change in their chemical composition.
Is evaporation of water off a lake a chemical change?
yes
