Which is an example of the kinetic-molecular theory not holding true for a gas?The average kinetic energy of particles depends only on the temperature.
The particles in a gas travel in straight lines in a continuous, random motion.
The attraction between particles causes a gas to condense at low temperatures.
The particles in a gas make up a small portion of the total volume of the gas.

Answers

Answer 1

Answer:

Answer: the third option, the attraction between particles causes a gas to condense at low temperatures

Explanation:

1) The kinetic-molecular theory explains the behaviour and properties of the gases in terms of the energy, size, and motion of its particles or molecules.

2) As per the size, the particles are considered to make a small portion of the total volume of the gas, to the point that their size is fully neglected (zero). The particles are considered to not occupy any space (volume) of the gas.

3) The first and the second statments are directly stated by the molecular-kinetic theory: a) the average kinetic energy of particles depends only on the temperature, and b) the particles in a gas travel in straight lines in a continuous, random motion.

Regarding the statement that the attraction between particles causes a gas to condense at low temperatures, this is not true.

First of all, the kinetic molecular theory of the gases is not valid at low temperatures and hight pressures.

Second, depending on the gas and the intermolecular force, at low temperarures a gas might condense or not. It depends on the attractive forces, which are neglected for gases by the molecular-kinetic theory.

Complete Question

The complete question is shown on the first uploaded image

Answer:

Explanation:

From he question we are told that

The first mass is $m_1 = 0.42kg$

The second mass is $m_2 = 0.47kg$

From the question we can see that at equilibrium the moment about the point where the string holding the bar (where $m_1 \ and \ m_2$ are hanged ) is attached is zero

Therefore we can say that

$m_1 * 15cm = m_2 * xcm$

Making x the subject of the formula

$x = (m_1 * 15)/(m_2)$

$= (0.42 * 15)/(0.47)$

$x = 13.4 cm$

Looking at the diagram we can see that the tension T on the string holding the bar where $m_1 \ and \ m_2$ are hanged is as a result of the masses ( $m_1 + m_2$ )

Also at equilibrium the moment about the point where the string holding the bar (where ( $m_1 +m_2$ ) and $m_3$ are hanged ) is attached is zero

So basically

$(m_1 + m_2 ) * 20 = m_3 * 30$

$(0.42 + 0.47) * 20 = 30 * m_3$

Making $m_3$ subject

$m_3 = ((0.42 + 0.47) * 20 )/(30 )$

$m_3 = 0.59 kg$

Which particle would produce a magnetic field?(1) a neutral particle moving in a straight line
(2) a neutral particle moving in a circle
(3) a stationary charged particle
(4) a moving charged particle

Answers

Answer: The correct answer is "a moving charged particle".

Explanation:

If the current flowing in the conductor then there is magnetic field around the wire which can be detected by the compass needle.

Here, the flow of charges which are negatively charged electrons produces the magnetic field. The flow of charges constitutes the electric current.

If there is no flow of the charged particles then there is no magnetic field produce. To produce magnetic field, it is necessary that charged particle must move.

From the given options, a moving charged particle would produce a magnetic field.

Therefore, the correct option is (4).

Neutral particles and stationary charged particles
don't produce magnetic fields.

Charged particles in motion do.

In a nuclear power plant, _____. energy is released from the nuclei of atoms energy is released from the bonds of molecules energy is released from the electrons of atoms energy is stored in the nucleus of atoms

Answers

In a nuclear power plant, energy is released from the nuclei of atoms. The correct option among all the options given in the question is the first option. Huge amount of thermal energy is released by the breaking of the uranium atoms. This energy is used for turning a turbine that produces electricity. It is a very clean method of producing electricity.

Answer: energy is released from the nuclei of atoms

Explanation:

Chemical energy is the energy stored in the bonds of molecules.

Nuclear energy is the energy stored in the nucleus of the atom.

Nuclear power plants use heat produced during nuclear fission to heat water which is produced by the splitting of heavy nucleus into lighter elements by release of energy.

The complete nuclear fission reaction is:

Explain the right-hand rule as it applies to rotation of winds around a high or low pressure center.

Answers

Explanation:

The right-hand rule, also known as the Buys-Ballot's law, helps explain the rotation of winds around high and low pressure centers in the Northern Hemisphere. According to this rule:

1. In a low pressure center (cyclone) in the Northern Hemisphere, the wind rotates counterclockwise around the low-pressure center. If you extend your right hand with your thumb pointing upwards, your fingers will curl in the counterclockwise direction, representing the direction of the winds.

2. In a high pressure center (anticyclone) in the Northern Hemisphere, the wind rotates clockwise around the high-pressure center. If you extend your right hand with your thumb pointing upwards, your fingers will curl in the clockwise direction, representing the direction of the winds.

This rule is based on the Coriolis effect, which is caused by the Earth's rotation. As air flows from areas of higher pressure to lower pressure, it is deflected by the Coriolis force due to the Earth's rotation. In the Northern Hemisphere, the Coriolis force deflects moving air to the right. This deflection, combined with the pressure gradient force, results in the counterclockwise rotation around low-pressure centers and clockwise rotation around high-pressure centers.

It is important to note that the right-hand rule is specific to the Northern Hemisphere. In the Southern Hemisphere, the opposite is true. The wind rotates counterclockwise around low-pressure centers and clockwise around high-pressure centers.

Understanding the rotation of winds around pressure centers is essential in meteorology for predicting weather patterns and systems. By studying these rotations, meteorologists can make informed forecasts and predictions about the movements and impacts of weather systems.
