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.
Is substance melts proof that a chemical change has occurred?
no unless there is a chemical change but there isn't. only a physical change has occurred
Why a solid substance melts to liquid at high temperature?
the possibility of a solid substance to melt depends on the bond present in the solid substance.at high temperature,most or some of the bonds present in the substance break,leading to vibration of the crystal lattice present in the substance,if the vibration within compound increase,there is a distortion and breaking down of the bonds present,making the solid substance attain a more stable state,that is in liquid form.
When a substance melts the temperature of the substance?
it decreases.
Why the melting point of a substance is a physical property but flammability is a chemical property?
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.
What happens to the atom or molecules of a substance if it melts?
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.

A metal melts at 450 degrees celsius is the property of the metal classified as chemical or physical property?
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.
Is An ice cube melts a physical change?
Yes it does not change the actual composition of the substance creating a new one.
Is substance melts proof that a chemical change has occurred?
no unless there is a chemical change but there isn't. only a physical change has occurred

Is it physical or chemical when ice melts?
physical
A substance melts at 375 Celsius What is the melting point on the Fahrenheit scale?
A substance melts at 375 Celsius. What is the melting point on the Fahrenheit scale?
When does a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
