Milk is normally a liquid(a suspension of cream droplets in water), by freezing it milk changes from a liquid to a solid. This is a physical change, the substance is still milk, however it is no longer a liquid, it has changed into a solid.
Yes , you have a liquid turning into a solid .
It is a physical change. When the water vapour inside of the freezer turns to frost (ice), it hasnt changed the fact that it is still water, just in a different form. Therefore, this is a physical change.
A physical change.
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
The change that occurred to the water is a physical change. In this case, the water changed from a liquid state to a solid state without altering its chemical composition.

Yes, evaporation is a physical change of phase.
Assuming you mean liquid water turning into gaseous water, that is a physical change, because it's still water (H2O.)
Changes of state are physical changes.
water turning into ice
Physical change, because the water is only changing state, from a gas to a liquid.
A physical change.
A physical change is something that does not change the chemical makeup of a substance. For example, water turning into vapor is a physical change because the composition is not changed. Water vapor still has hydrogen and oxygen just like water.

No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same.
