No, pine wood does not sink in water. It is less dense than water, so it will float on the surface.
Maple is a hard wood (from a leafed tree) and pine is a soft wood (from a conifer). In this case both wood also have the described character (hard vs soft) not always the case.
The easiest type of wood to cut is softwood, such as pine or cedar, because it is less dense and requires less effort to saw through compared to hardwoods like oak or maple.
There are various types of maple and pine each with its own characteristics but the main difference in characteristics is that maple is hard and fine grained whereas pine is relatively soft and coarse grained. There is a list of various types of wood and their characteristics at `Properties and Uses of Woods' - http://www.inquirewithin.biz/Vol1/Woods/wood_properties.htm.
pine wood burns very rapidly because it is not dense and is full of very flammable rosin.
Yes, pine wood is less dense than oil, so it would float on top of oil due to its buoyancy. Oil is less dense than water, so pine wood would also float on water.
