Upsc Rank Holders answered • 3 weeks ago Class 8 |
When electrodes are immersed in water and electricity is passed through it, water undergoes electrolysis. The water molecules are split into hydrogen and oxygen gases. The hydrogen gas is released at the negative terminal (cathode), and the oxygen gas is released at the positive terminal (anode). Therefore, the bubbles formed on the positive terminal are oxygen gas.

Sounak Sengupta answered • Nov 25, 2018 Class 8 |
Electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). The process is carried out in an electrolytic cell (q.v.), an apparatus consisting of positive and negative electrodes held apart and dipped into a solution containing positively and negatively charged ions. The substance to be transformed may form the electrode, may constitute the solution, or may be dissolved in the solution. Electric current (i.e., electrons) enters through the negatively charged electrode (cathode); positively charged components of the solution travel to this electrode, combine with the electrons, and are transformed to neutral elements or molecules. The negatively charged components of the solution travel to the other electrode (anode), give up their electrons, and are transformed into neutral elements or molecules. If the substance to be transformed is the electrode, the reaction is generally one in which the electrode dissolves by giving up electrons.
Electrolysis is used extensively in metallurgical processes, such as in extraction (electrowinning) or purification (electrorefining) of metals from ores or compounds and in deposition of metals from solution (electroplating). Metallic sodium and chlorine gas are produced by the electrolysis of molten sodium chloride; electrolysis of an aqueous solution of sodium chloride yields sodium hydroxide and chlorine gas. Hydrogen and oxygen are produced by the electrolysis of water.

Malavika Basu answered • Jun 27, 2020 Class 8 |
Nature of medium influences speed of sound the most.
Without a medium, there's no sound. Sound waves require a medium in which to travel from one place to another.
We know that a solid has its particles packed very tightly together. Liquid particles are more loosely packed, and particles in a gas are pretty far apart. The distance between the particles affects how strong the interactions are between them. This, in turn, affects how quickly they transfer the energy of the wave. The stronger the particle interactions are, the more quickly the wave is transferred. So in general, sound travels faster in solids than in liquids, and faster in liquids than in gas.

= ( a² + b² + c² - ab - bc - ca )
By multiplying it by 2 and dividing it by 2.
= 2 ( a² + b² + c² - ab - bc - ca ) ÷ 2
= ( 2a² + 2b² + 2c² - 2ab - 2bc - 2ca ) ÷ 2
= ( a² + a² + b² + b² + c² + c² - 2ab - 2bc - 2ca ) ÷ 2
= ( a² + b² - 2ab + b² + c² - 2bc + a² + c² - 2ca ) ÷ 2
= [ ( a - b )² + ( b - c )² + ( a - c )² ] ÷ 2
Now , whatever is the value of ( a - b ) , ( b - c ) and ( a - c ) but its square will be always positive, and 2 is also a positive number.
So, the sum of ( a - b )², ( b - c )² and ( a - c )² will be a positive number and if a positive number is divided by a positive number then the result is also a positive number.
So, it is a positive number,hence it can't be a negative number.

Explanation:
Pressure of the Atmosphere:
- When the bulb of the dropper is pressed, the volume inside the dropper decreases, causing an increase in pressure.
- This increase in pressure pushes the water out of the dropper.
Atmospheric Pressure:
- When the pressure on the bulb is released, the volume inside the dropper increases, causing a decrease in pressure.

How many natural numbers lie between 9² and 10²? Between 11² and 12²?
|
|
Kirti Choudhury answered • Sep 15, 2018 Class 8 |
Number of Natural Numbers between 9² and 10²:
To determine the number of natural numbers between 9² and 10², we need to find the count of integers from 10² - 1 to 9² + 1.
Step 1: Find the values of 10² - 1 and 9² + 1.
10² - 1 = 100 - 1 = 99
9² + 1 = 81 + 1 = 82
Therefore, we need to count the natural numbers between 99 and 82.
