Water can change from liquid to gas only through a chemical reaction true or false?

This is considered a physical change.
The distinction between physical and chemical changes are subtle and the line is not clear cut. Chemical changes tends to involve reactions and the rearrangement of bonds and atoms. Physical changes tend to involve changes in properties without a reaction, so water changing from a gas to a liquid is a change of state but it is still water, the only bonds that would be broken are weak intermolecular interactions.

Liquid to gas is not a chemical change it is a physical change. The water molecules do not change so no reaction occurs, the only difference Is that now the atoms are moving faster

water is changed from a liquid to a gas through boiling, which occurs at 100 degrees (Celsius)

∙ 12y agoWater turns to gas in a phase change called vaporization, which includes evaporation and boiling. Phase changes are physical changes, not chemical.

Is The colorless liquid ethanol burns in air a physical or chemical property?
ethanol is a type of alcohol, in the oxygenated hydrocarbon class of compounds. when it combines rapidly with oxygen in a combustion reaction, the ethanol is used up, and with oxygen forms carbon dioxide and water. ethanol is quite literally gone, it is broken down and reformed into new products, which is the definition of a chemical reaction.

Is boiling of liquid air a chemical reaction?
It is called the Fractional Distillation of Liquid Air. It consists of air being pumped into the industrial plant and filtered to remove dust. It is then passed through drying towers to remove the Carbon Dioxide and Water Vapor, which would clog the pipes. It is then compressed and cooled until the air is liquid. Some gases, such as helium, are removed since they remain in a gaseous state, and the liquid air is pumped into a fractionating tower and heated. The gases then boil off according to their boiling points, and are collected in separate tanks
Is liquid ammonia boiling a chemical or physical change?
Physical change.. think of it as it changing state not the substance
Silver melts at 961 Celsius Is it chemical change or physical change?
This is a physical change because you are changing it from a solid to liquid
Is burned ethanol a physical or chemical change?
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
When you mix water and jello powder and put it in the refrigerator and it congeals is it a chemical change?
No, it is a physical change. Jello changes from a liquid to a solid through colling not through a chemical reaction. If you reheat jello it can go back to its liquid form.
Is water changing from liquid to gas a chemical reaction?
No, water undergoing a phase change is a physical change, not a chemical change.
What happens to a substance during a chemical change or chemical reaction?
substances can change to a solid, gas or liquid. solid - precipitate gas - fumes liquid - color change Either way, since its a chemical reaction, there always will be a change in the chemical composistion of a substance.
When Liquid ethyl alcohol turns into a solid when placed in a low-temperature freezer a chemical reaction?
It does but it is Not a chemical change its physical change...
What caused the liquid to change to a gas?
- a chemical reaction with release of gas - eavaporation or boiling of the liquid at the the temperature of boiling
Is reaction with acid a physical or chemical property?
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
Setting of a jelly-is it a chemical change?
Yes, it is. This is because there is a physical change. Being a liquid forming a solid. There is a chemical reaction when the hot water is added to the powder, forming a liquid, which is cooled, forming a solid

It is a change in physicalness
What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
Is vinegar reacting with baking soda a physical change?
This is a chemical change. This is because it is a simple Acid - Base reaction; they neutralise one another to form a salt and water, along with carbon dioxide because baking soda is a carbonate.
