An increase of decrease in the amount of energy within that substance initiates the state change. For example the heat of fusion from ice to water is 334kj/kg which means if i have 1kg of ice at 0 degrees Celsius (or -32 Fahrenheit) I have to add 334kj of energy to it in order to change it to 1kg of water at 0 degrees.
Change Of Temperature. For Example; Water Freezes At Zero Degrees Celsius. Frozen Water (Ice) Melts Into Water (Usually) At Twenty Degrees Celsius; Try Holding It In Your Hands Or Mouth For About Five Minutes. Water Can Then Evaporate At Higher Temperatures Into Steam (Which Is Usually On Windows And Mirrors After You Get Out Of A Shower.
If the temperature is slightly less than zero degrees, it will freeze. If it is slightly more than zero degrees, it will remain as water. A temperature of exactly zero degrees, of course, can not be achieved - but in theory, it should keep its state. If it's already water, it should remain as water, if it's already ice, it should remain ice.
Solid.
Water freezes solid at 0 degrees Celsius, so it will still be solid at -24 degrees Celsius.
0 degrees centigrade for water to freeze 100 degrees centigrade for water to boil
gas
The freezing point of water is when it will change from a liquid state to a solid state; the freezing point of water is 0 C.
it depends on the substance. water freezes at zero degrees Celsius, 32 degrees Fahrenheit.
liquid
liquid
This is an example of physical equilibrium, because if you look at the two phases (physical property) of water at zero degrees C, they both exist. At 0ºC, the molecules of water go back and forth between being a liquid and a solid, thus the equilibrium.
Boil water to change it from liquid to gas. At sea level pure water changes state at 100 degrees Celsius or 212 degrees F.

It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.
