    If ice melts to water, do you think it is a physical or chemical change?

    Its actually physical. Water molecules in ice turns to water molecules in liquid water. Do you think heat is gain or lost when ice turns to water?

    Released=lost Absorbed=gain

    Ice gains heat to melt water Just like how the sun melts ice.

    So water vapor to liquid water loses heat energy. Liquid water to ice loses heat energy

    When you pick a choice, explain to me why you picked it and I will tell you.

    I think that it says that it will be D unless I am reading it wrong

    I will tell you if it is correct if you tell me why you pick D relating it to chemistry, not just "it makes sense","it said so","you explained it"

    I think that it is D because the diagram showed a physical change and not a chemical change
