Water changes from one state to another due to a change in temperature and pressure. When heat is added to ice, it gains energy, causing the molecules to move faster and break the hydrogen bonds, transitioning it into liquid water. Further heating causes the water molecules to move even faster, overcoming intermolecular forces, and transitioning it into water vapor. Similarly, decreasing pressure can also cause water to change states, such as when water boils at lower temperatures at higher altitudes due to the reduced atmospheric pressure.
A substance changes from one state of matter to another by either gaining or losing energy. For example, to change from a solid to a liquid, energy is added to break the intermolecular bonds. To change from a liquid to a gas, more energy is added to overcome the forces of attraction between the molecules.
The evaporation of water is an example of a physical change, where water changes from its liquid state to a gaseous state without any change in its chemical composition.
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.
Changing solid water (ice) into liquid water involves a physical change known as melting. This process requires the addition of energy to break the intermolecular bonds holding the ice molecules together, allowing them to move more freely and form a liquid state.
It is a change in state. For instance, water may undergo boiling to form water vapour. The reactants and products are chemically the same, which is H2O. Another example would be the sublimation of ammonium chloride, where it changes directly from a solid to a gas.The change from reactants to products is called as a chemical reaction. According to the key reaction involved there are several types of reactions. For example, an acid and a base undergo a neutralization reaction to produce a salt and water as products.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
True. Water can change from a solid state (ice) to a liquid state (water), and from a liquid state to a gaseous state (steam) depending on the temperature and pressure conditions.

It causes matter to change by turning the water into gas which is vaporization, turning water into ice.

water can freeze to a ice cube
The word "change" can be used with the phrase "of state" to describe a transition or transformation from one condition or form to another. For example, "The boiling water underwent a change of state to become steam."
You will know that it's a non-chemical change because: 1. Non-chemical changes do not form a new substance. 2. They are generally reversible. 3. They are not accompanied by considerable heat change.
