A gas initial volume and pressure is 5m^3 and 101320 Pa and allows to expand up to 12m^3 then what is the final pressure?
Answers
Answer:
New pressure = 42216.66 Pa
Explanation:
Given that,
Initial volume, V₁ = 5 m³
Final pressure, P₁ = 101320 Pa
Final volume, V₂ = 12 m³
We need to find the final pressure of the gas. We know that the relation between pressure and volume is given by :
So, the new pressure is equal to 42216.66 Pa.

Answer: The given statement is true.
Explanation:
When solid state of water changes directly into vapor state then this process is known as sublimation.
For example, when dry ice is placed at room temperature then it converts into vapor state without undergoing liquid state.
Also when we apply very high pressure or temperature at the solid state of water, it will change directly into vapor state.
Therefore, the statement ice does not need to melt into liquid water before it can return to the atmosphere as water vapor is true.
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation.

To solve this we must be knowing each and every concept related to direct relationship. Therefore, the value for each of the given points can be given as below.
What is direct relationship?
The relationship between the two supplied quantities can be used to construct one of two forms of proportionality. Direct proportion as well as inverse proportion are those. In mathematics, a direct proportion is indeed a comparison of two integers in which the ratio of both numbers equals a fixed amount.
According to the concept of proportion, two ratios are in proportion when they are equal. When an increase or reduction in one quantity causes an equivalent rise or fall in the other, the two quantities are said to be directly proportional.
Mathematically,
The x and y are directly related
k=8
x=0.5, y=4
x=1, y=8
x=2, y=16
x=3, y=2
Therefore, the value for each of the given points can be given as above.

Answer:
V = 0.167L
Explanation:
We can use the ideal gas law:
PV = nRT
where P, V, and T are pressure, volume, and temperature (Kelvin only). R is the gas constant and n is the moles of gas.
We want the volume of gas when the moles changes. Let's set up two equations, 1 for each state. Since both temperature and pressure are constant, we can simply use the terms P and T both states.
Initial (0.553 moles and 253 ml)): P*(0.253L) = (0.553 moles)RT
Second (0.365 moles, unknown volume, V): P*V = (0.365 moles)RT
P*(0.253L) = (0.553 moles)RT
P*V = (0.365 moles)RT
Lets set these up as a ratio:
P*(0.253L)/P*V = ((0.553 moles)RT)/((0.365 moles)RT)
P, T and R all cancel to 1, and the moles unit cancels:
(0.253L)/V = (0.553)/((0.365)
The ratio of the volumes is in direct proportion with the ratio of the moles.
Rearrange and solve:
(0.253L) = (0.553)/((0.365)V
(0.253L)*(0.365/0.553) = V
V = 0.167L

Acids are divided into two groups: Binary and Oxyacids. NAMING BINARY ACIDS: The name of the binary acid consists of two words. The first word has three parts: the “hydro” prefix the root of the nonmetal element the “ic” ending The second word is always “acid” Examples: HCl = hydro chlor ic acid = hydrochloric acid HBr = hydro brom ic acid = hydrobromic acid HF = hydro fluor ic acid = hydrofluoric acid 2. NAMING OXYACIDS: These are more difficult to name because these acids have hydrogen, a nonmetal, and may have varying numbers of oxygen atoms. For example, H2SO5, H2SO4, H2SO3, and H2SO2 are all acids. How do we name them? To begin, we need a point of reference. Our reference point is this: The “ate” ions (sulfate, nitrate, etc) make the “ic” acids (sulfuric acid, nitric acid) Examples: SO4 2- = sulfate ion H2SO4 = sulfuric acid NO3 - = nitrate ion HNO3 = nitric acid Once we have our point of reference, the acid with one more oxygen than the -ic acid is called the per-_________-ic acid. The acid with one less oxygen then the -ic acid is called the ___________-ous acid. If the acid has one less oxygen than the -ous acid, it is called the hypo-____________-ous acid. Examples: H2SO5 = persulfuric acid HNO4 = pernitric acid H2SO4 = sulfuric acid HNO3 = nitric acid H2SO3 = sulfurous acid HNO2 = nitrous acid H2SO2 = hyposulfurous acid HNO = hyponitrous acid The KEY:
