Question

A. fill in the blanks. 1. wax vapours from the candle burns to produce _______ and _______​

Answer 1

Answer:

heat and light

When we light a candle, the wax first melts and then gets partly vaporised. The vapours burn to give heat and light. Carbon dioxide, soot and water vapour are also produced.

Answer 2

Wax is used to make the candle. When the flame is produced by burning in the presence of air.

Explanation:

• The candle is a light source. When the wax from the candle combines with the oxygen in the air, carbon dioxide is produced. The wax burns, releasing heat and light.
• The flame is more likely to be produced by chemicals that can evaporate when burned. For example, kerosene or the melted wax responsible for the flame's production.
