Question

Define the following:

Vulcanization

(b)Nutrition
​

Answer 1

Explanation:

Vulcanization is the process carried out for the production of rubber. In this process, raw rubber is heated with a mixture of sulphur and an appropriate additive, at a temperature range of 61.85°C to 141.85°C for three to four hours. Sulphur is added to give toughness to rubber.

b . ) the process of nourishment of our body is called nutrition

Answer 2

Answer:

1 .Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.

2 .Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion. The science that studies the physiological process of nutrition is called nutritional science.
