The pressure and absolute temperature of an ideal gas are both tripled, the volume is __________. not changed

Physics

ankoles [38]3 years ago

Answer:

Not Changed

Explanation:

To know what happened with the volume you need to know the Ideal gas Law

\frac{P_{1}V_{1}}{T1} =\frac{P_{2}V_{2} }{T2}

This law is a combination of the other four laws: Boyles's, Charles's, Avogadro's, and Guy-Lussac's.

The initial state is represented by P1, V1, T1 and the final by P2, V2, T2.

In this case:

T_{2} =3T_{1} \\P_{2} =3P_{1}

Replacing on the equation

\frac{P_{1}V_{1}}{T1} =\frac{3P_{1}V_{2}}{3T_{1} }

If we clear from the equation V2

\frac{P_{1}V_{1}3T_{1}}{T_{1} 3P_{1}} ={V_{2}}

Then cancel both P1 and T1

\frac{3V_{1}}{3} =V_{2}

You will found that

V_{1} =V_{2}

Calculate the power provided by a 12 volt car battery with a rating of 350 amperes.
mamaluj [8]

Answer:

Option D

4200 W

Explanation:

Power, P is also given as the product of voltage and current, expressed as P=VI

Here, P is power, V is voltage in the xircuit and I is current theough voltage.

Taking 12 V for voltage across and 350A for current across circuit then power will be

P=350*12=4200 W

Therefore, option D is correct.

An ice-making machine inside a refrigerator operates in a Carnot cycle. It takes heat from liquid water at 0.0 ∘C and rejects he
Agata [3.3K]

Answer:

2.36 x 10^6 J

Explanation:

Tc = 0°C = 273 K

TH = 22.5°C = 295.5 K

Qc = heat used to melt the ice

mass of ice, m = 85.7 Kg

Latent heat of fusion, L = 3.34 x 10^5 J/kg

Let Energy supplied is E which is equal to the work done

Qc = m x L = 85.7 x 3.34 x 10^5 =  286.24 x 10^5 J

Use the Carnot's equation

\frac{Q_{H}}{Q_{c}}=\frac{T_{H}}{T_{c}}

Q_{H}=286.24\times 10^{5}\times \frac{295.5}{273}

QH = 309.8 x 10^5 J

W = QH - Qc

W = (309.8 - 286.24) x 10^5

W = 23.56 x 10^5 J

W = 2.36 x 10^6 J

Thus, the energy supplied is 2.36 x 10^6 J.

Why does the solar system consist of small planets orbiting close to sun and larger on more distant
ahrayia [7]

Answer:

The inner planets are smaller and rockier

Explanation:

Astronomers divide the planets into two groups in Solar system,  the  inner planets and outer planets. The inner planets are smaller and rockier and it is closer to the sun.  The outer planets are larger , further far away and made of gas

The inner planets are Mercury, Venus , Earth and Mars.  The outer planets Jupiter , Saturn , Uranus and Neptune comes after an  asteroid belt. In some other planetary systems the gas are close to the sun.

particles in a disk of gas and dust will form Planets.  If they orbit the star they are colliding and sticking.  The stars wind blows away their gases . So the nearest planets to starts are rockier.

The period of rotation of Mars is 1 day and 37 minutes. Determine its frequency of rotation in Hertz.
Sholpan [36]

The frequency of rotation of Mars is 0.0000113 Hertz.

<u>Given the following data:</u>

  • Period = 1 day and 37 minutes.

To find the frequency of rotation in Hertz:

First of all, we would convert the the value of period in days and minutes to seconds because the period of oscillation of a physical object is measured in seconds.

<u>Conversion:</u>

1 day = 24 hours

24 hours to minutes = 60 × 24 = 1440 minutes

1440 + 37 = 1477 \; minutes

1 minute = 60 seconds

1477 minute = X seconds

Cross-multiplying, we have:

X = 60 × 1477

X = 88620 seconds

Now, we can find the frequency of rotation of Mars by using the formula:

Frequency = \frac{1}{Period}\\\\Frequency = \frac{1}{88620}

<em>Frequency </em><em>of rotation</em> = <em>0.0000113 Hertz</em>

Therefore, the frequency of rotation of Mars is 0.0000113 Hertz.
