physical property because the chemical makeup of the ice remains the same
The fact that a metal (mercury) is a liquid at room temperature is a characteristic property of the metal, mercury. The temperature at which a metal melts to become liquid would be a chemical property of the metal.
chemical. when it melts, it doesn't mean it changed into a new substance. it just changed physical states! it is still a metal. physical state is a physical property of any substance, so when it changes physical state, as in changes to liquid, solid or gas, it is still the same substance.
Solder is a mixture of various metals. Its physical property is that it melts at fairly low temperatures, not so low that it melts when this is undesired. Its reactions are the same as the component metals.
Melting candle wax is a chemical change. Why? Because when you cook or burn candle wax it melts so it is a chemical change.
First of all, melting point is not a change at all, so forget about classifying it as a physical or a chemical change. It's a property and it's got nothing to do with the chemical composition of water since when water melts it's chemical nature does not change. Hence melting point of water is a physical property or characteristic.
Barium melts at 725°C. physical or chemical property
No. Melting point is a physical property.
chemical
The melting point is considered a physical property of materials.
The fact that a metal (mercury) is a liquid at room temperature is a characteristic property of the metal, mercury. The temperature at which a metal melts to become liquid would be a chemical property of the metal.
Physical because none of its chemical property's are not changed. Its still ice, just melted

When a substance melts, it changes state from solid to liquid. This does not alter the substance's chemical composition, so melting point is a physical property. Flammability means burning, and when a substance burns, it reacts with oxygen to produce a new substance that was not there before. This is therefore a chemical property.
Physical, Since only the property of the chocolate didn't change, after it melted, it still is chocolate
