Is a solid changing from a liquid to a gas a physical or chemical change?
The change of a liquid to a gas is a physical change because its chemical properties do not change. Molecules of the liquid are just moving farther apart, therefore turning into a gaseous state.
Is breath coming as a steam a physical change?
Don't take only my word for it, but, i think it would be a chemical change because if you think about it you are inhaling oxygen and exhaling carbon dioxide. Which would make it a chemical change, but I am not 100% positive.
What is the difference between a ohysical change and a chemical change?
A Physical Change is a change in the form of either gas, liquid, or solid while a chemical change is a change that occurs in the molecule such as the the burning of methane: CH4+2O2-->CO2+2H2O. Indicators of a Chemical reaction are: Heat, Light, pH, Color, Smell, ect. While Physical will be like ice melting into water or water being boiled into steam.
What is the new substances that are formed during physical change?
in a physical change, no new substance is formed. for example liquid water. You freeze it, it becomes ice. when you boil it, it evaporates into steam. HOWEVER. Steam, ice, or liquid, it is STILL water. You only form new substances in chemical changes: cooking/burning food, reacting chemicals etc. : )
What does steam rising from a compost bin mean?
evaporating from the garden
Is water evaporating into steam physical change and why?
Evaporation is a physical process because not involve any chemical process.
Is water evaporating into steam chemical or physical change?
It's a physical change because no new substances are formed, the molecules simply get further apart.
Is water evaporating into steam physical or chemical?
It's a physical change because no new substances are formed, the molecules simply get further apart.
Is water evaporating into steam a physical change and why?
it is a physical change. It's obvious becuase it is just a change of state
Is mixing popcorn steam a physical or chemical change?
it is a chemical change
Is water is heated and changed to steam a physical change or chemical change?
chemical
Is steam from a kedal a physica l or chemical change?
Steam from a kettle is a physical change.
When water changes to steam is it a chemical change?
No, it is a physical change.
Is steam turning to water a chemical or physical change?
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.
Is evaporation a chemical or physical change?
While boiling isn't the same as evaporation in that the entire liquid is heated to the point of steam and not just the surface molecules, the same physical change that causes evaporation can be seen in boiling. When boiled, a liquid becomes hot enough that it converts from that form into a gas, and if gathered and cooled, that gas reverts to its liquid form. For example, if a pot of boiling water is covered to trap the steam, that steam gathers on the inside of the cover where it again becomes water. This not the result of any chemical change in the water, just a change in its physical form.SO, EVAPORATION IS A PHYSICAL CHANGE.
Is steam a chemical raection?
NO!!!! It is a physical change of water from liquid to gas(vapour).
When water turns into steam is it a chemical change?
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
