Why is the melting point of a substance is a physical property but flammability is a chemical property?

Answer 1

In the state of matter you can use all five senses without having to change the substance (physical property). With chemical property you are altering the substance so you are able to observe it.

Answer 2

Because melting point is making it the same thing, like an icecube evaporating, its still the same thing, just in a different state. Flammability is creating a flame, making gas which is chemical

Answer 3

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.

Answer 4

The melting point of a substance is a physical property because it is determined by the arrangement and movement of the molecules within the substance. On the other hand, flammability is a chemical property because it describes how a substance reacts chemically with oxygen in the presence of heat to produce combustion.

Answer 5

Because when ice melts it does not change the ice's identity.

Answer 6

Because during the melting the structure of the molecule remain unchanged.

Answer 7

Melting doesn't involve the change of the chemical compostio or structure of a compound.
Burning is a chemical reaction, an oxydation.
