Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction
The rest of the wax melts with the increased temperature. That is the physical change.
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
it is a chemical change because it causing the fuel to burn
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.
One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.
There are multiple physical changes and chemical changes that occur when a candle burns. One physical change is that the candle melts back into liquid wax. One chemical change is flame burning on the wick.

Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
No, chemical changes and physical changes are distinct processes that occur separately in a system. Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the state or appearance of a substance without changing its chemical composition. These processes do not typically occur simultaneously.
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
The process of bees converting nectar into beeswax and then into honey involves both chemical and physical changes. Chemical changes occur during the conversion of nectar into beeswax and honey, while physical changes occur during the shaping, cooling, and solidification of the wax.
Physical, because it doesn't change chemical make up it just changes the appearance and texture
It is primarily a chemical change. However, physical changes also occur because of the chemical activity.
Brewing beer involves both physical and chemical changes. Physical changes include crushing grains and boiling water, while chemical changes occur during fermentation when yeast converts sugars to alcohol and carbon dioxide.
Because any chemical changes occur.
Mostly chemical, but physical changes also occur, such as when the windows blow out.
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
