physical: it's a change of state, it does not change the chemical makeup: molecular, atomic
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
A liquid at normal temperatures and pressures is a physical change. When a substance changes from a solid to a liquid or from a gas to a liquid without any chemical reactions taking place, it is considered a physical change.
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
The boiling of liquid nitrogen at -196 degrees Celsius is a physical change. This is because the change in state from liquid to gas does not involve a change in the chemical composition of the nitrogen molecules.
Melting wax is a physical property because it does not change the chemical composition of the wax when it transitions from solid to liquid state. The process just involves a physical change in the state of matter.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
No, changes of state such as this are physical changes.

The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.

It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
