A gas has a volume of 62.65L at O degrees Celsius and 1 atm. At what temperature in Celsius would the volume of the gas be 78.31
Anastaziya [24]

Answer:

The volume of the gas will be 78.31 L at 1.7 °C.

Explanation:

We can find the temperature of the gas by the ideal gas law equation:

PV = nRT

Where:

n: is the number of moles

V: is the volume

T: is the temperature

R: is the gas constant = 0.082 L*atm/(K*mol)

From the initial we can find the number of moles:

n = \frac{P_{1}V_{1}}{RT_{1}} = \frac{1 atm*62.65 L}{(0.082 L*atm/K*mol)*(0 + 273)K} = 2.80 moles

Now, we can find the temperature with the final conditions:

T_{2} = \frac{P_{2}V_{2}}{nR} = \frac{612.0 mmHg*\frac{1 atm}{760 mmHg}*78.31 L}{2.80 moles*0.082 L*atm/(K*mol)} = 274.7 K

The temperature in Celsius is:

T_{2} = 274.7 - 273 = 1.7 ^{\circ} C

Therefore, the volume of the gas will be 78.31 L at 1.7 °C.

I hope it helps you!

Which type of seismic wave can move through solid layers of the earth but not through
masya89 [10]

Answer:

S - waves

Explanation:

Secondary s-waves are elastic waves and they are part of the earliest waves that reach are seismic station.

Both  P and S -waves are the first set of waves to reach a seismic station after an earthquake event.

  • P waves are primary waves and they move through any kind of earth materials.
  • They transmitted longitudinally.
  • S - waves are secondary waves. These waves are shear waves and they cannot be propagated through liquids.

How would the tides on Earth be affected by the absence of the Moon?There would be no spring tides.
Dmitry_Shevchenko [17]
I think the best answer is: The tides would occur at a much lower intensity.
The forces that create tides include centrifugal forces from the earths rotation and also the gravitational force of the sun. Although these are much smaller than the force exerted by the moon we would still have tides.
