When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
When sodium melts is it a physical or chemical change?
When sodium melts, it undergoes a physical change. This is because the change in state from solid to liquid does not alter the chemical composition of the sodium itself. It remains as sodium in both the solid and liquid states.
Is it a chemical or physical change if a piece of ice melts and reacts with sodium?
Melting is a physical process; reaction with sodium is a chemical process.
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
Is melt a chemical or physical?
Melting is a physical change because it does not involve a change in the chemical composition of the substance. When a substance melts, its molecules or atoms move apart, resulting in a change in its physical state from solid to liquid.
When a chocolate bar melts in the sun is it a physical change or chemical change?
Physical, Since only the property of the chocolate didn't change, after it melted, it still is chocolate
When a chocolate bar melts in the sun is it a chemical or physical change?
Physical because on the appearance of the chocolate bar changed
Why is melting of ice cream a physical change?
Chemical Change!Because when chocolate start out as just chocolate but when it melts it becomes a chemical because its just something to drink like water,Water is a chemical beause its just something to drink,but you don't actuly drink chocolate,it just becomes a chemical because it melts in to a liquid and all liquids are just becomes a solid,so Chocolate is a chemical when it melts because its just like water but chocolate isn't water its just like water because it melts into a chemical!
When ice melts into water is that a physical or chemical change?
Physical Change
When the wick burns and the candle melts is it a chemical or physical change?
it is a chemical change
When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
When a cube of ice melts to form a puddle of water a chemical or physical change?
It is a physical change.
Is melting chocolate a reversible reaction why?
Yes. It's just like ice to water and back to ice. - - - - - "Reaction" implies a chemical change. Melting chocolate is a physical change. (Hardening melted chocolate can involve a whole series of physical changes but that's a different issue.)
Is it physical or chemical when ice melts?
When ice melts, it undergoes a physical change, not a chemical change. The molecules in the ice are still the same water molecules, but they are transitioning from a solid state to a liquid state.
Is it a chemical change when the sun melts a cryon?
No, melting is a physical change, not a chemical change. When the sun heats up and melts a crayon, it changes from a solid to a liquid state, but the chemical composition of the crayon remains the same.
When a chocolate bar melt in the sun is that a physical change or a chemical change?
When a chocolate bar melts in the sun, it is a physical change. This is because melting is a reversible process in which the chocolate changes from a solid to a liquid state due to the increase in temperature. No new substances are formed during this process, making it a physical change rather than a chemical change.
Is silver melts when using a blow torch a chemical or physical recation?
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
