Is the burning of a candle reversible or irreversible?
It's irreversible
How burning candle is irreversible?
When a candle burns, the wax is consumed and converted into energy and heat, releasing light and heat into the surroundings. This process cannot be undone as the wax is permanently changed into different molecules like carbon dioxide and water vapor. Once the candle has burned down, it cannot be restored to its original state.
Is a burning candle a reversible or non reversible change?
Burning a candle is a non-reversible change because once the wax is melted and the wick is burnt, it cannot be undone to return the candle to its original state. The chemical composition of the wax and wick is changed permanently.
What change of state is it when a candle wax becomes a liquid?
The change of state is melting. When a candle wax is heated, it transitions from a solid state to a liquid state.
Is burning candle a reversible or irreversible change?
Burning a candle is an irreversible change because the wax undergoes a chemical reaction with the oxygen in the air, producing new substances like carbon dioxide, water vapor, and ash. Once the candle has been burned, it cannot be restored to its original state.

What makes the candle solid in its physical state?

State of the wax after candle is lit?

Which is the only state of India from where uranium is obtained?

What kinds of energy are needed in this investigation to change the state of matter of the candle?
The energy needed to change the state of matter of a candle is primarily in the form of heat energy. When the candle is lit, the heat energy from the flame melts the candle wax, causing it to change from a solid to a liquid state. Further heating vaporizes the liquid wax, transforming it into gaseous wax molecules that combine with oxygen to produce light and heat energy.
Is a candle melting a physical change or a chemical change?
It is a physical change because when it melts it is still a candle just a melted one
How does the state of matter of wax in a candle change when the candle is lit an need an answer?
When a candle is lit, the wax melts into a liquid state due to the heat from the flame. The liquid wax is then drawn up the wick through capillary action and vaporizes into a gas, which is what burns to produce the flame.
