State whether the following statement is true or false:
During the burning of a candle,only a chemical change takes place.
During the burning of a candle,only a chemical change takes place.
(B) The statement is False.
When a candle burns,both physical and chemical changes occur simultaneously.
$1$. Physical Change: The wax near the flame melts due to heat,changing from a solid state to a liquid state. This is a physical change because the chemical composition of the wax remains the same.
$2$. Chemical Change: The melted wax (vaporized) reacts with oxygen in the air to produce carbon dioxide,water vapor,heat,and light. This is a chemical change because new substances are formed.
