An insulated container with a divider in the middle contains two separated gases. Gas 1 is initially at a higher temperature tha

n gas 2. The divider is then removed. Which of the following observations might be made over a period of time as the two gases mix together, and why
(A) Gas 1 remains at a higher temperature than gas 2 because gas 1 started at a higher temperature.
(B) Gas 1 remains at a higher temperature than gas 2 because gas 1 started with a higher kinetic energy.
(C) On average, the molecules of gas 1 lose all of their kinetic energy to the molecules of gas 2 through collision, resulting in gas 2 eventually having a higher temperature than gas 1.
(D) On average, the molecules of gas 1 lose some of their kinetic energy to the molecules of gas 2 through collisions, resulting in the two gases eventually having the same temperature.

Answer:

Option (D) On average, the molecules of gas 1 lose some of their kinetic energy to the molecules of gas 2 through collisions, resulting in the two gases eventually having the same temperature.

Explanation:

From the question given, Gas 1 was initially at a higher temperature than Gas 2.

As the two gas mixes together, there will be a transfer of heat from Gas 1 molecules to Gas 2 molecules. Now, as this continues over a period of time, the two gas will eventually have the same temperature.

Answer:

The correct answer is <u><em>(D) On average, the molecules of gas 1 lose some of their kinetic energy to the molecules of gas 2 through collisions, resulting in the two gases eventually having the same temperature.</em></u>

Explanation:

Molecular kinetic theory is a theory that postulates that matter is made up of a set of particles known as atoms or molecules, which are constantly in motion.  These particles collide continuously with each other and with the walls of the container that contains it. These collisions are carried out kinetically, in other words, energy is transferred without loss.

The kinetic energy of the particles increases with increasing temperature. In this case, gas 1 is initially at a higher temperature than gas 2.  So gas 1 has higher kinetic energy than gas 2.  Then, to reach an equilibrium when the mixture of both gases occurs, gas 1 must lose part of its kinetic energy, transferring it to gas 2 through particle collisions to reach the same temperature.

<u><em>The correct answer is (D) On average, the molecules of gas 1 lose some of their kinetic energy to the molecules of gas 2 through collisions, resulting in the two gases eventually having the same temperature.</em></u>

An industrial firm has two electrical loads connected in parallel across the power source. Power is supplied to the firm at 4000
Andrei [34K]

Answer:

I = 27.65A < 40.59°

PowerFactor = 0.76

Explanation:

Current on the heating load is:

I1 = 30KW / 4KV = 7.5A < 0°

Current on the inductive load:

I2 = (150KVA*0.6) /4KV = 22.5A  with an angle of acos(0.6)=53.1°

The sum of both currents is:

It = I1 + I2 = 7.5<0° + 22.5<53.1° = 27.65<40.59°

Now, the power factor will be:

pf = cos (40.59°) = 0.76

Which statement describes a controlled experiment?
olga_2 [115]

Answer:

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

A violin string vibrates at 260 Hz when unfingered. At what frequency will it vibrate if it is fingered one fourth of the way do
Advocard [28]

Answer:

346.66 Hz

Explanation:

l_1 = Length of string which is unfingered = l

l_2 = Length of string which is vibrate when fingered = l-\dfrac{1}{4}l=\dfrac{3}{4}l

f_1 = Unfingered frequency = 260 Hz

f_2 = Fingered frequency

Frequency is inversely proportional to length

f=\dfrac{1}{l}

So,

\dfrac{f_1}{f_2}=\dfrac{l_2}{l_1}\\\Rightarrow \dfrac{f_1}{f_2}=\dfrac{\dfrac{3}{4}l}{l}\\\Rightarrow \dfrac{f_1}{f_2}=\dfrac{3}{4}\\\Rightarrow f_2=\dfrac{4}{3}f_1\\\Rightarrow f_2=\dfrac{4}{3}260\\\Rightarrow f_2=346.66\ Hz

The frequency of the fingered string is 346.66 Hz
