Explain about pressure exerted by liquids and gases

Posted by Akshaya Dilli 2 years, 6 months ago

CBSE > Class 08 > Science

2 answers

Preeti Dabral 2 years, 6 months ago

The hydrostatic pressure is the pressure exerted by a fluid at equilibrium at any point of time due to the force of gravity. Hydrostatic pressure is proportional to the depth measured from the surface as the weight of the fluid increases when a downward force is exerted. Fluids exert pressure in all directions equally.

Preeti Dabral 2 years, 6 months ago

A fertiliser is an inorganic salt.Fertilisers are prepared in factories.they have all the three important plant nutrients nitrogen, phosphorous and potassium. They do not emit any bad smell but they cause alot of pollution.ex ammonium sulphate . A fertiliser does not provide any humus to the soil.
Manure is a natural substance obtained by the decomposition of cattle dung, human waste and plant residues. Manure is a natural product. it is prepared naturally in the field. And it mostly doesn't have the three important plant nutrients . Manure provides a lot of humus to the soil.

ANSWER

Boojho observed that copper is deposited on the electrode connected to the negative terminal of the battery. Paheli tried to repeat the same experiment. But she could find only one copper plate. Therefore she took a carbon rod as a negative electrode. Will copper be still deposited on the carbon rod? Explain your answer.

0Thank You

Vishal Kumar 2 years, 6 months ago

No, copper will not be deposited on the carbon rod used as a negative electrode in the experiment. This is because the deposition of copper on the electrode is a result of the reduction of copper ions present in the solution onto the electrode. The reduction of copper ions occurs at the negative electrode, which attracts the positively charged ions towards it. However, for the deposition of copper to take place, the electrode used as the negative terminal should be made of a material that has a lower reduction potential than copper. Copper has a reduction potential of -0.34 V, which means any electrode with a reduction potential lower than -0.34 V can be used as the negative electrode. Carbon has a reduction potential of -0.22 V, which is higher than the reduction potential of copper. This means that carbon is not a suitable material for the negative electrode in this experiment, as it cannot attract the copper ions from the solution and reduce them to form a copper deposit. Therefore, even if Paheli uses a carbon rod as the negative electrode, copper will not be deposited on it as it does not have a lower reduction potential than copper.

Define asexual reproduction describe two method of asexual reproduction in animal with the help of diagram

. . 2 years, 6 months ago

Asexual reproduction is the type of reproduction in which only one parent is involved. The two methods of Asexual reproduction are as follows - 1) Binary fission - when one unicellular organism splits into two daughter individual. The nucleus of the parent organism splits into two nuclei. The cytoplasm also divides into two and each contains one nucleus. A constriction is formed so deep that it divides the organism in two. For eg - amoeba 2) budding - In this, a small outgrowth or projection called bud is formed on the body of the parent. The nucleus of the parent organism is divided into two and one goes to the bud. The bud then grows and detaches from the body of the parent and grows as an individual. For eg - hydra.

Write five sources of air pollution and their effects on living organisam

Posted by Riya Saini 2 years, 6 months ago

CBSE > Class 08 > Science

1 answers

Preeti Dabral 2 years, 6 months ago

There are four main types of air pollution sources: mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.

Harmful effects of air pollution depend on the concentration of pollutants, duration of exposure to the pollutants and types of pollutants that caused pollution.

In plants, it causes fruit damage, leaf damage, chlorosis, necrosis, mottled spots on leaves, less yield of crops and causes premature death of plants, etc.
In humans, it causes respiratory ailments like asthma, hay fever, allergic diseases, etc., cancer and genetic mutations.
Carbon monoxide (CO) released as a pollutant can combine with haemoglobin thus, preventing the supply of O₂ to the cells and causing death due to asphyxiation because it leads to damage of the brain.
The burning of fossil fuels, exhaust from automobiles, etc., release SO₂ and NO₂into the atmosphere. These gases are oxidised to sulphuric acid and nitric acid in the air. They get dissolved with the rainwater falling on the earth and form acid rain.
The various vehicle such as car, buses, trucks running on petrol release harmful gases.
