Is a candle melting a reversible change or irreversible change?
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
Is melting wax physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
Is candle wax melting physical property?
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
What is the melting candle wax that is dripping down the side of the candle an example?
The melting candle wax dripping down the side of the candle is an example of a physical change. This occurs when the solid wax is heated and transitions into a liquid state due to the heat from the flame.
A melting candle demonstrates which reaction?
A melting candle is an example of a physical change, not a chemical reaction. The process involves a solid candle turning into liquid wax due to the application of heat, with no change in the chemical composition of the wax molecules.
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 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 candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
How are ice and the wax of a candle alike?
Ice and the wax of a candle are both solids at room temperature. They can both change states, with ice melting into liquid water and candle wax melting into liquid wax when heated. Additionally, both ice and candle wax can be used to cool or absorb heat in various applications.
Is a candle melting chemical or physical?
The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.
Is a candle burning reversible or irreversible?
irreversible change.
How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
