What is an ideal gas?

1 answer:

7 0

An ideal gas is a theoretical gas composed of a set of point particles with random displacement, which do not interact with each other. The ideal gas concept is useful because it behaves according to the ideal gas law, a simplified equation of state, which can be analyzed using statistical mechanics.

The equation of state of a classical ideal gas is given by:

$PV=nRT$

Where:

P = pressure

V = Volume

n = amount of substance

T = Temperature

R = Ideal gas constant

Why is the answer B? I'm not sure which equation to look at when doing these proportion types of problems.

loris [4]

Explanation:

Given:

Δy = d

v₀ = 0

a = g

Find: v

v² = v₀² + 2aΔy

v² = (0)² + 2(g)(d)

v = √(2gd)

If we double d:

√(2g (2d))

√(4gd)

Compared to the first velocity:

√(4gd) / √(2gd)

√2

So the new velocity is √2 greater than the first velocity.

√2 v

If i have a mass of 58.0 kilograms what is my weight

liraira [26]

You would be 127.86 lbs. approx. One kilogram is equal to 2.20 pounds, so you just multiply kilos into the conversion rate. If you are trying to convert pounds to kilos, divide your pounds into the conversion rate.

Hope that helped! :)

A uniform thin rod of mass ????=3.41 kg pivots about an axis through its center and perpendicular to its length. Two small bodie

vivado [14]

Answer:

The length of the rod for the condition on the question to be met is $L = 1.5077 \ m$

Explanation:

The Diagram for this question is gotten from the first uploaded image

From the question we are told that

The mass of the rod is $M = 3.41 \ kg$

The mass of each small bodies is $m = 0.249 \ kg$

The moment of inertia of the three-body system with respect to the described axis is $I = 0.929 \ kg \cdot m^2$

The length of the rod is L

Generally the moment of inertia of this three-body system with respect to the described axis can be mathematically represented as

$I = I_r + 2 I_m$

Where $I_r$ is the moment of inertia of the rod about the describe axis which is mathematically represented as

$I_r = \frac{ML^2 }{12}$

And $I_m$ the moment of inertia of the two small bodies which (from the diagram can be assumed as two small spheres) can be mathematically represented as

$I_m = m * [\frac{L} {2} ]^2 = m* \frac{L^2}{4}$

Thus $2 * I_m = 2 * m \frac{L^2}{4} = m * \frac{L^2}{2}$

Hence

$I = M * \frac{L^2}{12} + m * \frac{L^2}{2}$

=> $I = [\frac{M}{12} + \frac{m}{2}] L^2$

substituting vales we have

$0.929 = [\frac{3.41}{12} + \frac{0.249}{2}] L^2$

$L = \sqrt{\frac{0.929}{0.40867} }$

$L = 1.5077 \ m$

What do geographers explore

Yakvenalex [24]

Answer:

Geographers explore both the physical properties of Earth's surface and the human societies spread across it. They also examine how human culture interacts with the natural environment, and the way that locations and places can have an impact on people.
