Are phase changes in chemistry physical changes?
YES
Is phase changes physical or chemical?

Are melting butter and melting ice cream are both physical change or chemical change?
They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
Why are changes in phase physical?
Because the substance is physically changing.
How does the physical property of water change?
