Answer ( Option A)

3.1 & 1200 to 1500 °C

Solution

Properties of Asbestos
The various properties of Asbestos that make it a viable engineering material are enumerated under
(a) Asbestos has a high tensile strength.
(b) It is a superior electrical insulator.
(c) Due to its incombustibility, it serves as a good heat insulator.
(d) It resists attacks by acids.
(e) It is non-porous, soft, and elastic.
(f) Its melting point ranges from 1200 to 1500 °C, and it is fire-resistant.
(g) Since it adheres well to cement, the fibre can be utilized as a fibre reinforcement.
(h) It is resistant to rusting.
(i) It has a specific gravity of 3.1.
(j) It is simple to cut into pieces.
(k) The length of the fibres has a significant impact on their quality.
(l) It has a silky and glassy smoothness.
