water changes to steam by the process called evaporation
that is a physical change because the steam is still water vapor.
When you boil water on the stove until it turns to steam you are witnessing a change in phase of matter/phase change of the water.
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
No, it's a physical change, for you can change steam back to its original state, water
yes
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
NO!!!! It is a physical change of water from liquid to gas(vapour).
evaporation
No, it is a physical change.
Heat from the nuclear reaction changes water to steam.
evaporation
Cool it!
When you boil water on the stove until it turns to steam you are witnessing a change in phase of matter/phase change of the water.
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
Heat from the nuclear reaction changes water to steam.
The change from liquid water to steam is a physical change in the state of matter. Evaporation is the term for a liquid becoming a gas.
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
You need to cool it down.
