Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

Glass tubed or glass tubing are hollow pieces of various glass types with a large variety of applications which are laboratory glassware. They can be cut into various sizes.

Glass is a non-crystalline amorphous solid that is often transparent. Since it is non-crystalline it is brittle in nature. Also, it does not react with chemicals.

________ can replace wood in cement bonded particle board.

  1. Rice straw

  2. Glass

  3. Wheat straw

  4. Paper
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rice straw can replace wood in cement bonded particle board.

rice straw-wood particle composite boards were manufactured as insulation boards using the method used in the wood-based panel industry. The raw material, rice straw, was chosen because of its availability. The manufacturing parameters were: a specific gravity of 0.4, 0.6, and 0.8, and a rice straw content (10/90, 20/80, and 30/70 weight of rice straw/wood particle) of 10, 20, and 30 wt.%. A commercial urea-formaldehyde adhesive was used as the composite binder, to achieve 140-290 psi of bending modulus of rupture (MOR) with 0.4 specific gravity, 700-900 psi of bending MOR with 0.6 specific gravity, and 1400-2900 psi of bending MOR with a 0.8 specific gravity. All of the composite boards were superior to insulation board in strength.

Tippu Sultan's sword was made from a variety of steel with high carbon content, which is called as ____.

  1. Carbon steel

  2. Stainless steel

  3. Alloy steel

  4. Wootz steel
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tippu Sultan's sword was made up of the Wootz steel, which was manufactured in Southern India. Wootz Steel is produced by a method known in ancient India. The process involved preparation of porous iron, hammering it while hot to release slag, breaking it up and sealing it with wood chips in a clay container, and heating it until the pieces of iron absorbed carbon from the wood and melted. The steel thus produced had a uniform composition of 1–1.6% carbon and could be heated and forged into bars for later use in fashioning articles, such as the famous medieval Damascus swords.

The stems and leaves of grasses are rough due to

  1. Calcium carbonates

  2. Resins

  3. Silica

  4. Calcium oxalate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The grass leaves are linear in shape and sessile and are rough in texture due to the presence of cork cells in the epidermis and deposition of silica material. The process of deposition of silica material over the epidermis is known as silicification. It checks the transpiration rate and prevents the entry of pathogens and gives stiffness to the lamina.

So, the correct answer is option C.

The walls and ceiling of an auditorium are covered with a fibrous material to

  1. Make the auditorium fire proof

  2. Absorb sound and prevent echoes

  3. Give an ethnic look to the auditorium

  4. To prevent leakage of water from the roof
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  We know that soft , porous and fibrous materials are good absorbers of sound , so they are used to the walls and ceiling of an auditorium to absorb the sound .

    If this is not done , sound waves after reflections (echoes) from walls and ceiling , will interfere and due to this at some places in auditorium , sound will not be heard (destructive interference) and at some places intensity of sound will be very large (constructive interference)
