A fire breaks out and increases the Kelvin temperature of a cylinder of compressed gas by a factor of 2.4. What is the final pre

kherson [118]

Answer:

P(final) is 2.4 times P(initial).

Explanation:

Here we can assume that the cylinder did not break and it's volume and number of moles of gas present in the cylinder remains constant.

Given the temperature increases by a factor of 2.4. Let us assume that the initial temperature be $T_{1}$ and the final temperature be $T_{2}$ .

Given that $T_{2}=2.4\times T_{1}$

Now we know the ideal gas equation is PV=nRT

here V=constant , n=constant , R=gas constant(which is constant).

$\frac{P}{T}=constant$

$\frac{P_{1} }{T_{1}}=\frac{P_{2} }{T_{2} }$

$P_{2}=(\frac{T_{2} }{T_{1} } )P_{1}$

$P_{2}=(\frac{2.4T_{1} }{T_{1} } )P_{1}$

$P_{2}=2.4\times P_{1}$

3. A ray of light consisting of blue light (wavelength 480 nm) and red light (wavelength 670 nm) is incident on a thick piece of

Alex Ar [27]

Answer:

The angular separation between the refracted red and refracted blue beams while they are in the glass is 42.555 - 42.283 = 0.272 degrees.

Explanation:

Given that,

The respective indices of refraction for the blue light and the red light are 1.4636 and 1.4561.

A ray of light consisting of blue light (wavelength 480 nm) and red light (wavelength 670 nm) is incident on a thick piece of glass at 80 degrees.

We need to find the angular separation between the refracted red and refracted blue beams while they are in the glass.

Using Snell's law for red light as :

$n_1\sin\theta_1=n_2\sin\theta_2\\\\\theta_2=\sin^{-1}((\dfrac{n_2}{n_1})\sin\theta_1)\\\\\theta_2=\sin^{-1}((\dfrac{1}{1.4561})\sin(80))\\\\\theta_2=42.555$

Again using Snell's law for blue light as :

$n_1\sin\theta_1=n_2\sin\theta'_2\\\\\theta'_2=\sin^{-1}((\dfrac{n_2}{n_1})\sin\theta_1)\\\\\theta'_2=\sin^{-1}((\dfrac{1}{1.4636 })\sin(80))\\\\\theta'_2=42.283$

The angular separation between the refracted red and refracted blue beams while they are in the glass is 42.555 - 42.283 = 0.272 degrees.

Gulls are often observed dropping clams and other shellfish from a height to the rocks below, as a means of opening the shells.

kumpel [21]

Answer:

v = 17.71 m / s

Explanation:

We can work this exercise with the kinematics equations. In general the body is released so that its initial velocity is zero, the acceleration of the acceleration of gravity

v² = v₀² - 2 g (y -y₀)

v² = 0 - 2g (y -y₀)

when it hits the stone the height is zero and part of the height of the seagull I

v² = 2g y₀

v = Ra (2g i)

let's calculate

v =√ (2 9.8 16)

v = 17.71 m / s

Explanation:

H₂ + Cl₂→ 2HCl chemical reaction

In a chemical reaction, a chemical change occurs when new kinds of products are formed. The products contains the atoms that are combining together and they obey the law of conservation of matter.

In a chemical reaction, elements, compounds and molecules are involved.

The reaction depicted is a typical combination or synthesis reaction in which two species reacts to form products. New compounds are formed

H + H → He + n nuclear reaction

In a nuclear reaction, nuclides combines or they are disintegrated due to their instability.

The above reaction is a typical nuclear fusion reaction in which light hydrogen atoms combines to form a heavy nuclide of helium. The reaction involves the transmutation and production of new element.
