<h2>
Answer</h2>
The volume will be<u> 50 L</u>
<h2>
Explanation</h2>
From Kelvin Law of Temperature, we know that
We know that
= 200 L
= 100 K
= 400 K
So,
The answer of the givern question is 50L

Explanation:
Answer:Answer: Mendeleev's table of elements was better accepted than those of other scientists at the time because it predicted correctly the properties of elements that had not yet been discovered. Moseley went a step further in suggesting that the elements be arranged according to atomic number
Explanation:
Answer:
Moles of water in 7.1×10²⁵ molecules are 118 mol.
Explanation:
Given data:
Number of molecules of water = 7.1×10²⁵ molecules
Moles of water in 7.1×10²⁵ molecules = ?
Solution;
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
1 mole = 6.022 × 10²³ molecules of water
7.1×10²⁵ molecules of water × 1 mol / 6.022 × 10²³ molecules of water
1.18×10² moles of water 0r 118 moles of water
<span>Hydroelectric energy uses the movement of water to spin a turbine and produce electricity. Coal is a fossil fuel that is burned as an energy source, which results in emissions such as carbon dioxide, nitrogen, and sulfur. Coal use is associated with waste products both from the mining process to acquire the coal and also from the actual use of coal itself. Hydroelectric energy does not involve waste, but does pose potential problems to waterways. Coal use is more common than the use of hydroelectric energy.</span>
