What are examples of items that their compound changes without changing their chemical composition?
Water and Ice.
Why is ice melting a physical property?
The Ice melting is not changing the chemical composition of Ice, it's still H2O When water becomes ice aswell
What makes ice a chemical change?
Water changing into ice does not have a chemical reason, as it is not a chemical reaction but a physical change. It changes its state of matter once reaching the freezing point of 0 degrees Celsius, and freezes.
Does melted ice represent a chemical change?
no its a physical change because its changing from a solid to a liquid and its still water!
Is melting ice cubes physical or chemical?
It is PHYSICAL because when the ice cubes melt, they turn into water. We can reverse the change and bring the water back into ice. Water has a chemical formula of H2O and so does ice. So, Physical Change: can be reversable, the object's components don't really change.
Is ice melting a chemical change or physical change?
Physical; it's changing from one state of matter to another
Solid changing into a liquid such as ice changing to water?
Melting.
Is water a physical or chemical change?
Water changing from liquid to solid (ice) or gas (steam) is a physical change, as the chemical composition of water remains the same. However, when water undergoes electrolysis to produce hydrogen and oxygen gas, it is a chemical change as the chemical composition of water is altered.
Is this a chemical change or physical change water freezes and turns into ice?
It's a physical change because the substance is the same before and after only changing form. In other words, water's chemical formula is H2O and ice's chemical formula is also H2O, so they are the same substance. Therefore it is a physical change.
What is the chemical symbol for ice?
The chemical symbol for ice is H2O, which represents the water molecule. Ice is the solid phase of water, where water molecules are arranged in a crystalline structure.
Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
Why is water freezing into ice a physical change?
You can always undo a physical change by reversing the process. i.e. when you freeze water it turns into ice and when you heat the ice it turns back into water. Therefore it is a physical change.
