When lpg comes out from the cylinder turns to liquid to gas.is this a chemical change?
The process of LPG turning from liquid to gas is a physical change, not a chemical change. It involves a change in state, from liquid to gas, without any alteration in the chemical composition of the LPG molecules.
Is water vapor turning to rain an example of a chemical change or physical change?
Physical change, because the water is only changing state, from a gas to a liquid.
Is solid a physical or chemical change?
Neither. A physical change is changing something's tangible properties, such as shape or state of matter (solid, liquid, or gas), while a chemical change is turning something into something else entirely. For example, water freezing into ice is a physical change, but cake batter turning into cake is a chemical change. So, if it's the same thing that you start with as a liquid or gas and it simply becomes a solid, it's a physical change. If it becomes something else entirely, it's a chemical change. I hope that helped.
Is melting a slice of cheese a chemical change?
It is changing from a solid to a liquid, which is a physical change.
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 butter turning hard when cooled a physical change?
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so 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 pouring liquid a chemical change or physical?
A physical change.
Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
Is steam turning into water chemical or physical?
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
Do the bubbles in a pot of boiling water for noodles indicate chemical change?
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
Is liquid to a gas chemical or physical change?
it is a change of state, a physical change.
