0 degrees centigrade for water to freeze

make it cold or make it hot
take a hot bath then water turns to steam
None.
it is a physical change because the state of the glass does not change.it cracks because of the rapid change of temperature
Adding hot water to pot noodles is a physical change. The hot water causes the noodles to absorb the water and soften, changing their physical state without altering their chemical composition.
Hot Water
Mixing coffee with hot water is a physical change because the individual substances (coffee and water) retain their chemical identities and only the physical state of the coffee changes, dissolving in the water. No new substances are formed.
Physical. The glass expands or contracts depending on temperature, when you put a hot glass into cold water part of the glass cools and contracts while some of it is still in it's hot, expanded state.
Dissolving sugar in hot water is a chemical change.
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
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.
Heating water to make it hot is a physical change, as the water's chemical composition remains the same. The change in temperature simply affects the kinetic energy of the water molecules, causing them to move faster and appear hot.
