What Changes Occur When A Candle Burns. Cooler areas are darker and colored orange, red, or brown. The heat of the flame produces an updraught of air that draws the flame into its familiar shape. Melting and vaporisation are physical changes. When a candle burns the burning wick evaporates the wax into the air. In a burning candle, wax is drawn up the wick by capillary action and evaporates, so what is burned is a gas. This is because the wax oxidizes or burns to yield water and carbon dioxide. Lighting the candle wick initiates the physical change to the candle wax. The melted wax soaks into the wick & is pulled upwards into the flame by capillary action. Describe and explain what happens when a candle burns. When you burn a candle, it changes the physical state of the wax from a solid to a liquid to a gas. Candle wax starts as a solid. Heat from the flame melts the wax. Water vapor and carbon dioxide gas dissipate in the air around the candle in a reaction that also yields light and heat. Students will be able to: When a candle burns, wax in the candle melts and is then vaporised as it is drawn up the wick.

Cooler areas are darker and colored orange, red, or brown. Describe and explain what happens when a candle burns. In a burning candle, wax is drawn up the wick by capillary action and evaporates, so what is burned is a gas. Most of the flame's heat is delivered toward the tip, where a large volume. When you light the wick, the flame generates heat. When you burn a candle, you end up with less wax after burning than you started with. When a candle burns, what changes take place? Melting and vaporisation are physical changes. The heat of the flame produces an updraught of air that draws the flame into its familiar shape. Students will be able to:

Describe and explain what happens when a candle burns. Heat from the flame melts the wax. The basic burning of a candle happens as follows. Lighting the candle wick initiates the physical change to the candle wax. In zero gravity there is no ‘up’ and a flame forms a sphere.
