what state of matter is present at the melting point of a substance
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
no unless there is a chemical change but there isn't. only a physical change has occurred
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.
it decreases.
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.
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
When a cube of ice melts to form water, it undergoes a physical change. This is because the substance remains water in both states, but changes from a solid form (ice) to a liquid form (water) due to a change in temperature.
It is a physical reaction. Melting is a physical change because it does not change the chemical composition of the substance.
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.
Yes it does not change the actual composition of the substance creating a new one.
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.

Barium melts at 725°C. physical or 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.
