There are quite a few examples of physical change including melting ice. You can also consider freezing water and boiling water a physical change.
The classical example is water with 3 phases: solid, liquid, gas. The transition is called change of phase

it goes from water (a liquid) to water vapor (a gas)! the 3 main physical states are solid, liquid and gas, so when it goes from one to another, this is defined as a physical change. you're welcome.

A physical change in contrast to a chemical change is one in which the chemical structure of the compounds involved are left unchanged. Only a physical change occurs. One such example is boiling water. This changes the physical state of water from a liquid to a gas. Similarly, freezing water is a physical reaction. In this case, liquid is frozen to form a solid.
Examples of polar molecules include: Water - H2O. Ammonia - NH. Sulfur dioxide
That depends on your definition of producing something new. If you cut lumber to build a table ... you have produced something new, but that is a physical change. Wood is still wood. But if you mean combining two or more substances, like hydrogen gas and oxygen gas, and, after burning, you form water, then that is a chemical change.
A physical property is a measurable characteristic of an item that is determined by its appearance. A sentence with it would be "More than one physical property of the substance changed when it became a gas."
When a substance changes phase, this is a physical changerather than a chemical change. When water freezes to become ice, or when ice melts to become water, its all physical.
