The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
Melting snow is a physical change because it involves a change in the state of water from a solid (ice/snow) to a liquid form, without altering the chemical composition of the water molecules. This change is reversible, as the melted snow can refreeze back into ice under appropriate conditions.
The reversible change is coffee dissolving in water. Boiling water, melting chocolate, and burning wood are irreversible changes.
No, a lava lamp is not a reversible change. The melting and mixing of the wax and oil inside the lamp is a physical change that cannot be easily reversed to its original state.
No, burning wax is an irreversible change. When wax is burned, it undergoes a chemical reaction that changes it into different substances (carbon dioxide, water vapor, and heat) that cannot be easily reversed.
Yes, melting snow is reversible. When the temperature drops, the melted snow can refreeze and turn back into ice or snow. This process is known as refreezing.
The melting of a candle is a reversible change because the solid wax can be cooled and solidified again to form a new candle.
Melting is a reversible change of state, whereas a chemical change is irreversible.
metal melting is a reversible change because as soon as you make the melted metal and freeze it, it might not come back the way it was but at least it is still the same metal material that you had.
Melting snow is a physical change because it involves a change in the state of water from a solid (ice/snow) to a liquid form, without altering the chemical composition of the water molecules. This change is reversible, as the melted snow can refreeze back into ice under appropriate conditions.
Yes, the icecream can be frozen again.
Freezing water is reversible because you can get it back to its original state by melting it - it turns back into water.
The reversible change is coffee dissolving in water. Boiling water, melting chocolate, and burning wood are irreversible changes.
No, a lava lamp is not a reversible change. The melting and mixing of the wax and oil inside the lamp is a physical change that cannot be easily reversed to its original state.
Processes that are reversible are physical changes. An example is the melting of ice.
Yes
A reversible change is where like if you had some ice, you could melt and then change it back to ice again making it a reversible. An irreversible change is something that can't be reversed, like burning food, as you cannot unburn it. Hope I helped!
