Is boiling water a physical or chemical change?

Boiling waterBoiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). If the bubbles were caused by the decomposition of a molecule into a gas (such as H2O →H2 and O2), then boiling would be a chemical change.

Heat can also change a material, Like candle change as it is heated it melts into a liquid . Melting is merely a change in form but substance remains the same such as the wax.

What happened to sugar and salt after heating it in 3 minutes?

Continuing to heat the sugar at high temperature causes these sugars to lose water and react with each other producing many different types of compounds. sugar melted faster. Sugar has low melting point or sugar melted faster . salt has slow melting ponit?

What happened to the white sugar after heating it?

Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar’s atoms to combine with the oxygen in the air, forming new groups of atoms.
