When ethyl alcohol evaporates is it a chemical or physical change?
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
Is burning coal for a barbecue physical or chemical change?
Burning coal for a barbecue is a chemical change because the coal undergoes a chemical reaction with oxygen in the air to produce heat and light, along with byproducts like carbon dioxide and ash.
Is burning coal for a barbecue a physical change?
Yes, burning coal for a barbecue is a chemical change. This is because the combustion process results in a chemical reaction where the coal combines with oxygen to produce heat, carbon dioxide, and other byproducts.
When alcohol evaporates is that a chemical or physical change?
Physical; from liquid to gas, but it's still alcohol.
Is drying cloths is chemical change?
It is a Physical Change because i dont know but im sure that is a physical change :P

Is dissolving in water a chemical or physical property?
Dissolving in water is a physical property because it does not change the chemical composition of the substance. The molecules of the substance are simply surrounded by water molecules and dispersed throughout the solution without undergoing a chemical reaction.
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 dissolving salt in water a physical or chemical change?
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
Why is dencity a physical change?
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.
Are dishes drying a chemical or physical change?
It's a physical change. The water on the plates evaporates to make water vapour, but it is still water, it hasn't changed chemically, it has just changed state from liquid to gas.
Is the ability to dissolve in water a physical property or a chemical property?
Its A physical change. When you boil water under a stove, The water evaporates and the chemical stays in the..pan or whatever you put in it.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
