What effect will the number of particles and temperature have on the rate of diffusion of gas molecules?

Chemistry
1 answer:
xxTIMURxx [149]2 years ago
7 0

Answer: option B - The rate of diffusion increases with the increase in number of particles and temperature.

Explanation:

Gases belong to the states of matter. They are made up of particles loosely attached, and traveling through the entire space of their containing vessel. These travels is known as DIFFUSION.

An INCREASE in TEMPERATURE and PARTICLES would DEFINITELY increase rate of TRAVEL (as particles tends to escape through any available space).

For Example: You must have noticed that on blowing more air into a BALLOON, It tends to burst. So, also heating a gas containing vessel, it EXPANDS and soon burst.

So, the RIGHT ANSWER is option B

Explanation:

1.

Given parameters:

Frequency of the radiation  = 8.4 x 10¹⁴Hz

Unknown:

Energy of the wave  = ?

Solution:

The energy of a wave is given by the expression below;

    E  = hf

E is the energy

h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s

f is the frequency

 Now insert the parameters and solve;

 E  =  6.63 x 10⁻³⁴m²kg/s x 8.4 x 10¹⁴Hz

 E  = 5.57 x 10¹ x 10⁻²⁰J

 E  = 5.57 x 10⁻¹⁹J

   

2.

Given parameters:

Wavelength = 2.13 x 10⁻¹³m

Unknown:

Frequency of the wave = ?

Solution:

The frequency of a wave can be determined using the expression;

     C  = f∧

C is the speed of light = 3 x 10⁸m/s

f  is the frequency

∧ is the wavelength

      f  = \frac{C}{wavelength}   = \frac{3  x 10^{8} }{2.13 x 10^{-13} }   = 1.41 x 10²¹hz

What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment?
Nataly_w [17]

The glass opposite to the negative electrode started to glow. Hence, option B is correct.

<h3>What is a cathode ray tube?</h3>

A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface.

J.J. Thomson, through his famous Cathode ray experiment, proved that all atoms contain small negatively charged particles known as electrons. In the experiment, he applied electric voltage across a cathode ray tube. a fluorescent material coating was done on the positive side. When the voltage was applied, the positive side has glowing dots.

Hence, option B is correct.
