4. Refractory timber catches fire readily while non-refractory timber does not catch fire readily.
Explanation: Timber is classified into types with respect to fire-resistance. These are refarctory and non-refractory. Refractory timber does not catch fire readily while non-refractory timber catches fire readily.
5. Which chemical is used in the coating of timber surface in Sir Abel’s process?
a) Dilute solution of sodium silicate
b) Concenterated solution of sodium silicate
c) Dilute solution of aluminium nitrate
d) Concenterated solution of aluminium nitrate
Explanation: Dilute solution of sodium silicate is used in the coating of the timber surface in Sir Abel’s process. This is a method that is adopted to make timber more fire-resistant.
6. In stud partitions, a stud of short length is known as ______
Explanation: In stud partitions, there are vertical members called studs and horizontal members called noggings. A stud of short length is known as puncheon. It is usually provided on an opening.

8. In trussed partitions, additional member provided between the head and sill is known as __________
Explanation: In trussed partitions, additional member provided between the head and sill is known as inter-tie. It is used to impart strength and rigidity. Exmet and bricktor are forms of reinforcements used in reinforced brick partitions. Nogging is a horizontal member of the timber framework.
9. Inclined members provided in the framework of trussed partitions are known as _________
Explanation: Inclined members provided in the framework of trussed partitions are known as braces. Its framework is quite similar to the framework of stud partitions but braces and steel bolts are additionally used.

a) Arsenic pentoxide
b) Arsenic sulphate
c) Copper sulphate
d) Potassium dichromate
