no
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.
No, a change of state is not a chemical change, for it can be changed back to its original form and their is no change in the molecular composition of the substance. A chemical change is when it cannot be changed back. The above example is an example of a physical change. Example:- ice when heated changes into water and water when cooled changes into ice.
correct! distillation is the prosses of evaporating a liquid to purify it then recondence it back to a liquid. This prosses can be used for removing salt from water.
Materials that do not go back to their original state after strectching are called inelastic or non-elastic elements. eg:-brick, iron etc.
Liquid water changes to water vapor in a process called evaporation. Evaporation is defined as the spontaneous change of liquid molecules into a gasseous state.
when ice was solid change liquid because sun was very hot. ice will change liquid change back solid again
melt it
I dont knao of an liquid sensig material but perhaps one of the temperature sensitive materials would do if the liquid you are sensing does not have the same temperature as the substrate on which you coul apply the liquid crystals that change color according to temperature (there are many in a wide array of temperature sensitive ranges)
condensation
an egg
You have to cool it.
This change is called condensation.
The phase change for liquid to gas is vaporization, which includes evaporation and boiling.Evaporation - The change of liquid molecules on the surface of a liquid to a gas.Boiling - The change of phase at or above the boiling point of the liquid, which takes place at nucleation sites within the liquid.
This equipment is called condenser.
A solid, or even a gas. And back again (improved)liquid is a state of matter, which can be a solid, liquid, or gas. therefore, liquid can be changed into a solid or a gas. to do so, just change the temperature of the matter. :-D
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
liquid changes to gas through the process of evaporation. then when a gas changes back into a liquid it goes through the process of condensation
