There are many physical properties for a piece of wood.
It is:
A solid
An insulator
Less dense than water (usually)
A liquid can be poured.A liquid will take the shape of its container.The molecules are quite free to move.Hope this helps!
a physical change is anything that can be undone. for example: -melting an ice cube (the water can be refrozen into the ice cube) -bending a piece of metal (the metal can be bent back into shape) -moving a block from one place to another (it can be moved back)
A liquid has a definite volume but an indefinite shape. It takes the shape of its container.
Lustrous, (meaning shiny) Maleable, (meaning that it can be pounded into shape), and Conductive (meaning that it can conduct electricity or transfer electrons) another property is Ductile (meaning that it can be stretched into a wire)
Cleaned, moistened, heated
list three physical sourcses of energy
If you actually mean the three states of matter, then your answer is liquid, solid, and gas. Plasmas and Bose-Einstein condensates are two other states of matter, extreme heat and extreme cold respectively, but you probably do not need to worry about those.If you actually mean physical properties, then your answer is probably based off of a test or worksheet or something like that for school, because there are way more then just three physical properties.

Three chemical properties are reactivity, flammability, and oxidation state.
The most important principle was the listing in groups, after similar chemical or physical properties.
Color, shape, texture, size, and density.
Mass, length, volume, amount of time for which it can be lit,
It's a fruit. It's red, yellow or green. It's edible.
Color, volume, harness, net weight...
melting points, solubility, and electrical conductivity
The wikipedia article is a good start and has a list of references at the end.
1-) get your own answer 2-) buy your website lmao jk 3-) idk the answer
