It is found that the most probable speed of molecules in a gas at equilibrium temperature

kaheart [24]

Answer:

$\frac{T_2}{T_1} = 1$

Explanation:

The root mean square velocity of the gas at an equilibrium temperature is given by the following formula:

$v = \sqrt{\frac{3RT}{M} }$

where,

v = root mean square velocity of molecules:

R = Universal Gas Constant

T = Equilibrium Temperature

M = Molecular Mass of the Gas

Therefore,

For T = T₁ :

$v = \sqrt{\frac{3RT_1}{M} }$

For T = T₂ :

$v = \sqrt{\frac{3RT_2}{M} }$

Since both speeds are given to be equal. Therefore, comparing both equations, we get:

$\sqrt{\frac{3RT_1}{M} }=\sqrt{\frac{3RT_2}{M} }\\\\\frac{T_2}{T_1} = 1$

Could a mixture be made up of only elements and no compounds. if so explain

Irina18 [472]

I racked my brain for almost 10 minutes, until suddenly,
it hit me !

You're breathing one right now ! So am I .

Air is a mixture of a lot of elements.
Nitrogen, Oxygen, and Argon account for 99.964 percent.

The other 0.036 percent is mainly Neon, Helium, Krypton,
and Hydrogen ... more elements.

Then there are Carbon Dioxide and water vapor.
Yes, those are compounds. But together, they add up
to very little of the air we breathe, and if both of them
suddenly disappeared, we would hardly notice it.

What is the external-internal pressure difference when the diver's lungs are at a depth of 6.1m (about 20ft)? assume that the di

Nesterboy [21]

Snorkel connects the diver's lungs with the air above the water. Because of this, the pressure inside the diver's lungs is the same as the atmospheric pressure.
The static pressure of a fluid is given with this equation:
$P=\rho gh$
The density of water is 1000kg/m^3.
$P=1000\cdot 9.81 \cdot 6.1=59841$Pa$
Standart atmospheric pressure is 101<span>325Pa.
</span>The difference is:
$\Delta P=101325-59841=41484 $Pa$

State the dimension of surface tension

Luda [366]

Answer:

Actually, surface tension is the to force per unit length. That means formula for surface tension is = force/length . As we know that the dimensional formula for length is L . And that for force is MLT^-2. So the dimensional formula for surface tension can be obtained by dividing the dimensional formula of force and length.
