Which is a clue that ice melting into water is a physical change?

Stick a thermometer into the water. When it boils, the temperature remains at 100oC/212oF. When it freezes, the temperature remains at 0oC/32oF. Evaporation takes place all the time in liquid state, so there would not be a way to check it. Other observations would be bubbles when boiling. When freezing, I suppose the water would be less transparent as it slowly hardens.

GOOD LUCK!!!!!!
It is change of the state of matter: from solid water to liquid water, not a chemical reaction.

How do you know that something has been though a physical change clues?
The clue for a physical change is that it only changes in a "physical" way, but it is still the same chemically. Ice melting (still water). Metal bending (still metal). Glass breaking (still glass).
Is wax melting a chemical or physical or chemical property?
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.

Why is it important to check for more than one clue before deciding if a change is physical or chemical?
It may be tricky deciding between physical and chemical changes, but if you look closely enough you can tell easily. For example, if the question is "Is ice melting a physical or chemical change?" it might seem like a chemical change because the ice changes drastically, but if you look for the additional clue that the water can revert back to ice, then you know it is a physical change. (A physical change is reversible) Most importantly though, remember: 1. A physical change is reversible, and only changes the appearance etc. of the thing in question. (Even salt dissolving in water is a physical change since the salt retains it's chemical identity of NaCl and can be retrieved from the water by evaporation.) 2. A chemical change is something that completely alters the identity of the substance. For example, when you cook eggs, the eggs are completely changed chemically and cannot revert back to they way they were before.
When can you say that a chemical change has happened to an object clue to heat?
The simplest example is when you boil water for a while and all you are left with is calcium (or whatever minerals and salts there are in the water). Heat has changed the physical state of water from liquid to gas (steam) and the object that was earlier a pot of water is now not ...

The temperature at which a substance changes from a liquid to a solid is the?
This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.
