In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. Which postulate of ki

netic molecular theory best explains how this is possible?
A. Attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly.
B. Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.
C. Gases consist of a large number of small particles, with a lot of space between the particles.
D. Gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Answer:

Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.

Explanation:

When a gas is paced in a container, the molecules of the gas have little or no intermolecular interaction between them. There is a lot of space between the molecules of the gas.

The gas molecules move at very high speed and collide with each other and with the walls of container.

The collision of these particles with each other is perfectly elastic hence the kinetic energy of the colliding gas particles do not change.

23) What is the volume of 2.454 x 1024 atoms of nitrogen gas at STP?
earnstyle [38]

Answer:

d) V =  91.3 L

Explanation:

Given data:

Volume of nitrogen = ?

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Number of atoms of nitrogen = 2.454×10²⁴ atoms

Solution:

First of all we will calculate the number of moles of nitrogen by using Avogadro number.

1 mole = 6.022×10²³ atoms

2.454×10²⁴ atoms × 1 mol / 6.022×10²³ atoms

0.407×10¹ mol

4.07 mol

Volume of nitrogen:

PV = nRT

1 atm × V = 4.07 mol ×0.0821 atm.L /mol.K ×273.15 K

V =  91.3 atm.L /1 atm

V =  91.3 L

What is the wavelength of an electromagnetic wave that has a frequency of
Alik [6]

Answer:

B

Explanation:

To calculate questions like this, you need to make use of the equation below:

ν = c / λ

ν is the frequency, c is the speed of light, and λ is the wavelength

ν = c / λ

2.45 • 10^9 Hz = (3•10^8 m/s)/(λ)

λ = 0.122 m = B

Consider formula A to be v = StartFraction 2 pi r over T EndFraction and formula B to be v2 = GStartFraction 2 pi r over T EndFr
MissTica

Answer:

The formulas that will be used are:

Situation one:

The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.

Gravitational force = GMm /r²

Centripetal force = mv²/r

Equating,

GMm/r² = mv²/r

v² = GM/r

The first scenario will use the formula v² = GM/r

Situation 2:

The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.

v = 2rπ/t
