I a liter jar contains 0.5 moles of gas at a pressure of 2 ATM what is the temperature of the gas
Answers
Answer:
The temperature of the gas is 48.75 Kelvin.
Explanation:
Using the ideal gas equation as shown
PV = nRT where;
P is the pressure of the gas in ATM
V is the volume of the gas
n is the number of moles
R is the ideal gas constant
T is the temperature in Kelvin
From the formula,
Given the following parameters V = 1litre, n = 0.5moles. pressure = 2ATM
R = 0.08206 atm L/molK
On substituting to get the temperature we have:

Answer:
V solids > V liquids > V gas
Explanation:
Speed of sounds depends of the type of material in which it travels, this phenomenon may be determined by the following formula:
V = √(B/ρ)
Where:
V= speed of sound
B= represent the medium hardness, this coefficient is expressed in Pascal units. The bigger the number, the hardest the material and sound travels faster. This is because in hardest material, particles are closer together so sound travels faster
ρ= density, for this case, for a high density value, sound travels slower
Both factors (B and P) should be considering when calculating the speed of sound
For example, for iron, B has a high value so sound travels faster, but also has a high density (this would make sound travels slower), but for this type of materials, B is much more bigger that P, hence V will be always a high number
Actually : V solids > V liquids > V gas
ρ is also important in certain circumstances, for example, in a gas, when temperature rises, P decreases, for which speed is faster in hot air
Solid medium helps sound waves to travel the fastest since the molecules inside a solid are closer to one another, allowing better transmission.
Explanation:
Talking about the motion of sound waves through the three phases of mediums (solid, liquid and gas), sound waves chose to be the fastest while travelling through the solid media.
Because in solids, the molecules are stacked closely to one another, allowing the transmission of sound waves faster as compared to the liquids or gases. In fact in air, the sound waves find clumsy to travel.
Sound waves travel about 17 times faster in steel than through air. Although there are always some exceptions yet, most of the solids provide better transmission of sound waves as compared to other mediums.

An increase in the velocity of an object will increase the momentum of the object.
What is momentum?
The momentum of an object is determined from the product of mass and velocity of an object.
P = mv
where
- m is the mass of the object
- v is the velocity of the object
Thus, an increase in the velocity of an object will increase the momentum of the object.

From your equation, we can tell that you're defining the upward direction as
positive. We can also tell that you threw the stone upward, with an initial speed
as it left your hand of 128 feet per second, about 87 miles per hour ... a mighty toss indeed, and I think there's a man from the Chicago Cubs waiting outside
who'd like to talk to you.
Anyway, When the stone splashes into the water, h(t) = 0 .
-16t² + 128t + 32 = 0
Divide each side by -16 :
t² - 8t - 2 = 0
I don't see any easy way to factor the expression on the left,
so I have to use the quadratic formula to solve this equation.
t = 4 plus and minus √18 .
t = +8.24 seconds
t = -0.24 second
Mathematically, both numbers are valid solutions.But when you apply
the equation to a real world situation, only the positive 't' makes sense.
So t = 8.24 seconds.

The potential energy of each kg of water, before it falls, is
(M G H) = (1kg) (9.8 m/s²) x (30 m) = 294 joules
The potential energy lost by 60 kg of water pouring through is
(60 x 294) = 17,640 joules
The power output of the plant is
(17,640 joules/sec) x (85%) = 14,994 watts
= almost but not quite 15 kW.
(If you used 10 for gravity, it would come out to 15.3 kW)
