melting point
The high melting point of tungsten (3422°C) is the physical property that makes it suitable for making filaments in tungsten light bulbs. This property allows the filament to reach high temperatures without melting, resulting in the efficient emission of light.
No, the color of ink is a physical property, as it relates to the way light is absorbed and reflected by the ink molecules. Chemical properties describe how a substance interacts with other substances in a chemical reaction.
It is a physical property. A chemical property would involve the butter reacting to the toast, but the butter is actually reacting to the heat from the toast. The butter would melt against any surface hot enough, where as butter would not melt on cold toast. Hence, the reaction to heat makes it a physical property. (A relatively easy way to remember is that physical properties deal with the transfer of physical energy or force such as heat, inertia, etc. Chemical properties occur when two material substances trade molecules or electrons.)
Yes, reactivity to water is a chemical property of copper, not a physical property. Copper does not react with water at room temperature, but it can slowly react with water when exposed to high temperatures or steam to form copper oxide.
One chemical property for Iron is that it conducts heat. One physical property is that it's malleable(it can be spread or shaped by being pounded with a hammer or by being forced with rollers).

no
Melting point is a physical characteristic of matter.
It has a high vapor pressure (it is volatile).
Its extreme hardness.
The concept of elasticity is a physical property because force can mutate a physical item and then when that force is removed and elastic object returns to its original form.æ Using elasticity to explain non physical phenonmena is a misnomer.
Because the mass depends on the size of an object.
No, the color of ink is a physical property, as it relates to the way light is absorbed and reflected by the ink molecules. Chemical properties describe how a substance interacts with other substances in a chemical reaction.
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.
That would be the wavelength/frequency
It is a natural magnet that attracts iron.
