How do i know whether something is a physical or chemical property?
Take this candle for example, it displays both physical AND chemical properties.
the melting of wax and vapourisation of melted wax are physical changes. On the other hand, the wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light.
I see the difference now! Physical is like a change to the eye, while chemical is the changing of a substance.
