Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.

Boiling water has a higher temperature than ice. Boiling water is heated to 100 degrees Celsius (212 degrees Fahrenheit), while ice is typically at 0 degrees Celsius (32 degrees Fahrenheit).
Dew is formed when water vapor in the air condenses onto a cool surface, such as grass or leaves, whereas steam is water vapor that is produced when water is heated to its boiling point. Dew usually forms overnight or early in the morning, while steam is typically seen when cooking or boiling water.
Water vapor is the gaseous state of water, while steam specifically refers to water vapor that is formed when water is heated to its boiling point. Therefore, while they both consist of gaseous water molecules, steam is specifically the visible mist that forms when water boils.
Gasoline has a less boiling point (72 degree Celsius) While water has a bigger boiling point (100 degree Celsius)
No, salt does not evaporate in boiling water. When water boils, it turns into steam, leaving behind the salt in the water. Salt does not have a low enough boiling point to evaporate along with the water.
If a kettle is overfilled while boiling, the boiling water can overflow, causing a mess and potentially a safety hazard. It is best to ensure there is enough space in a kettle to accommodate the water expanding as it boils.
The boiling point of water is dependent on environmental factors and the presence of solutes. In this case the pressure of the system on the water serves to increase the boiling point of water. The higher pressures increase boiling points while lowering pressure decreases it.
Water has a higher boiling point than alcohol. The boiling point of water is 100°C, while the boiling point of alcohol (such as ethanol) is lower, around 78°C.
No, adding salt to water increases its boiling point, while adding sugar does not have a significant effect on the boiling point of water.
steam is to liquid as smoke is to fire
