Explanation:
- PHYSICAL CHANGE IS ONE IN WHICH THE ONLY THE PHYSICAL PROPERTIES OF A SUBSTANCE CHANGE AND ITS CHEMICAL COMPOSITION REMAINS THE SAME MEANWHILE WHEN WE BURN CANDLE IT'S PHYSICAL PROPERTIES ARE CHANGED SUCH AS SHAPE , COLOR AND SIZE
- A CHEMICAL CHANGE IS ONE IN WHICH A NEW SUBSTANCE IS FORMED SO WHEN WE BURN CANDLE IT CHANGE'S INTO MELTED WAX ( A NEW SUBSTANCE ) . OTHER THAN THIS IN CHEMICAL CHANGE IS ENERGY IS ALSO RELEASED AND ABSORBED WHICH TRULY HAPPENS DURING THE BURNING OF CANDLE
EXAMPLE :
Burning of wood is an example of both chemical and physical change
