What is burning candle it is physically Chang or chamically?
Burning a candle involves a chemical change, as the wax is being oxidized by the oxygen in the air to produce heat, light, carbon dioxide, and water vapor. This process is irreversible and results in the formation of new substances, which is characteristic of a chemical change.
Name the different states of matter in which burning candle wax can resist?
Burning candle wax is in the liquid state as it melts, then transitions to a gaseous state as it vaporizes and combusts to produce a flame.
What are the Qualitative observation before and during burning of a candle?
Before burning, the candle appears solid, with a wick protruding from the top. During burning, the candle's wax melts and the wick ignites, producing a flame and releasing heat and light. The flame may flicker and produce smoke as it consumes the wax.
What happens to the matter of a burning candle after it burns?
The matter of a burning candle is transformed into heat, light, and various gases and particles, such as carbon dioxide, water vapor, and soot. The process is a chemical reaction in which the wax of the candle combines with oxygen from the air to produce heat and light.
Can burning a candle be reversible?
No, burning a candle is not reversible. When a candle is burned, the wax is melted and the wick is consumed, resulting in irreversible changes to the candle's structure.
Who discovered using a candle and a jar he observed that plants produce a substance that kept the candle burning?
Priestley
What is the thing that relies on burning to produce light and heat?
A candle relies on burning to produce light and heat. The wick of the candle is lit, and the heat from the flame melts the wax, which is then drawn up the wick and burned to produce light and heat.
Who concluded that plants produce a substance that can keep a candle burning?
Jan Ingenhousz
How does a candle produce carbon dioxide while it burns?
Any burning (oxidation reaction) produce carbon dioxide.
