Answer 1

Hardwood comes from deciduous(leafy) trees. Its used for flooring and indoor furniture
ex: oak, maple, teak, ash

Question 2

Softwood

definition & examples

Answer 2

Softwood comes from coniferous(evergreen) trees. Its used for construction and outdoor furniture.
ex: pine, spruce

Question 3

Modified woods
(definition & examples)

Answer 3

Modified wood is made by putting different scraps of wood together and uses glue,plastics & preservatives
ex: plywood, particle board, mdf

Question 4

Hardness Property for wood

Explain

Answer 4

Healthier trees have a higher level of hardness. Moisture content varies among, and cold temperature increase hardness. Rot affects the hardness of wood.

Question 5

Elasticity Property for wood

Explain

Answer 5

Wood has good elasticity. It can suffer many impacts without being permanently deformed. Defects and rot also reduces the elasticity.

Question 6

Resilience Property for wood

Explain

Answer 6

When wood has adequate moisture content it is resilient and resistant to breakage. When
wood is dry, it breaks easily.

Question 7

Ductility Property for wood

Explain

Answer 7

Wood has very little to no ductility. It can scarcely be stretched at all.

Question 8

Malleability Property for wood

Explain

Answer 8

Heat increases the malleability of wood. A plank or piece of wood can be bent if it is heated
to a certain amount.

Question 9

Tensile strength Property for wood

Explain

Answer 9

Wood has excellent tensile strength so it is often used to support heavy loads. Hardwood
has more tensile strength than softwood. Rot decreases the tensile strength of wood.
