List the methods of prevention of corrosion and rancidity

Posted by Mohit Sharma 5 years, 7 months ago

CBSE > Class 10 > Science

Meghna Thapar 5 years, 6 months ago

Corrosion is the process in which metals are eaten up gradually by the action of air, moisture or a chemical (such as an acid) on their surface. Rusting of iron metal is the most common form of corrosion. During the corrosion of iron, iron metal is oxidised by the oxygen of air in the presence of water (moisture) to form hydrated iron oxide called rust.

The condition produced by aerial oxidation of fats and oils in foods marked by unpleasant smell and taste is called rancidity. It spoils the food materials prepared in fats and oils which have been kept for a considerable time and makes them unfit for eating.

Methods to prevent rancidity:

(i) Rancidity can be prevented by adding anti-oxidants to foods containing fats and oils.

(ii) It can be prevented by packaging fat and oil containing foods in nitrogen gas.

(iii) Rancidity can be retarded by keeping food in a refrigerator.

(iv) Rancidity can be prevented by storing food in air-tight containers.

(v) Storing foods away from light can also prevent rancidity.

The French artist, Fredrick Sorrieu prepared a series of four prints visualising his dream of the world made up of 'democratic and social republics'. They have been used to symbolise the fraternity among the nations of the world. In Sorrieu's utopian vision, the peoples of the world are grouped as distinct nations, identified through their flags, and national costumes. Sorrieu created the image to unify the disintegrated states into a nation state under a democratic constitution.

Ph change as cause of tooth decay Why

Posted by Ritesh Meher 5 years, 7 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 6 months ago

pH change - Cause of tooth decay:

Tooth decay starts when the pH in the mouth falls below 5.5. Tooth enamel is made up of calcium phosphate which is the hardest substance in the body. It is insoluble in water but gets corroded when the pH in the mouth falls below 5.5. The bacteria present in the mouth produce acids due to the degradation of sugar and food particles after eating. Hence, to prevent tooth decay, the mouth should be rinsed after eating food and toothpastes which are basic should be used for cleaning teeth to neutralise the excess acid.

What is primitive farming?

Posted by Ankit Singh Thakur 5 years, 7 months ago

CBSE > Class 10 > Social Science

1 answers

Yogita Ingle 5 years, 7 months ago

Primitive Subsistence Farming: This type of farming is practiced on small patches of land. Primitive tools and family/community labour are used in this type of farming. The farming mainly depends on monsoon and natural fertility of soil. Crops are grown as per the suitability of the environmental condition.

This is also called <i>‘slash and burn’</i> agriculture. A patch of land is cleared by slashing the vegetation and then the slashed plants are burnt. The ash; thus obtained is mixed with the soil and crops are grown.

This type of farming produces just enough crops to sustain the family. After a couple of seasons, the patch is left fallow and a new patch of land is prepared for farming. This allows the earlier patch of land to replenish its fertility through the natural process.
