Biosphere: The living spaces of living and non-living things are called habitats.
Ecosystem: They are natural areas where living and non-living interactions occur.
Hydrosphere: Water is sphere. It is the layer formed by water bodies such as oceans and seas in the world.
Lithosphere: It is a stone sphere. It is the layer formed by rock and terrestrial regions in the world.
Atmosphere: Air is sphere. It is the layer on Earth where we can breathe and absorb ozone rays. The troposphere consists of the stratosphere, the mesosphere, and the thermosphere.

A sample of helium has a volume of 12.7 m3. The temperature is raised to 323 K at which time the gas occupies 32.5 m3? Assume pr

jasenka [17]

Answer: The original temperature was

$T_{1}=126.51K$

Explanation:

Let's put the information in mathematical form:

$V_{1}=12.7m^{3}$

$T_{1}=?$

$V_{2}=32.5m^{3}$

$T_{2}=323K$

$P_{1}=P_{2}=3atm$

If we consider the helium as an ideal gas, we can use the Ideal Gas Law:

$PV=nRT$

were <em>R</em> is the gas constant. And <em>n</em> is the number of moles (which we don't know yet)

From this, taking $R=0.08205746\frac{atm.l}{mol.K}$ , we have:

$n=\frac{P_{2}V_{2}}{RT_{2}}$

⇒ $n=3.67mol$

Now:

$T_{1}=\frac{P_{1}V_{1}}{nR}$

⇒ $T_{1}=126.51K$

Justify why sound waves need a medium to propagate with example??

Lana71 [14]

Answer:

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
