Increasing temperature increases the number of collisions and the potential energy of the colliding molecules and

1 answer:

3 0

Increasing temperature does increase the amount of collision but it increases the kinetic energy of the molecules not the potential energy. Potential energy brings molecules together or apart (depending) and kinetic energy makes the molecules move around or not. Hope this helps

525L

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

Mathematically;

$\frac{V1}{T1} = \frac{V2}{T2}$

V and T are the volume and temperature

Now we can solve the given problem;

$\frac{V}{T}$ = 1.75

Since temperature is given as 300K

Input the variables:

$\frac{V}{300}$ = 1.75

V = 1.75 x 300 = 525L

calculate the speed of an electron if its de broglie wavelength is twice its displacement in one second

valkas [14]

Answer:

The speed of an electron is 0.01908 m/s.

Explanation:

De-Broglie wavelength is given by:

$\lambda=\frac{h}{mv}$

where, $\lambda$ = wavelength of a particle

h = Planck's constant = $6.626\times 10^{-34}Js$

m = mass of particle

v = velocity of the particle

Velocity of an electron = v

Mass of an electron = $9.1\times 10^{-31}kg$

Wavelength of electron is twice the displacement in seconds which is velocity of an electron.

Then.wavelength of an electron = $\lambda =2v$

$\lambda =2v=\frac{6.626\times 10^{-34}Js}{9.1\times 10^{-31}kg\times v}$

v = 0.01908 m/s

The speed of an electron is 0.01908 m/s.

How many structures are possible for a octahedral molecule with a formula of ax4y2?

vekshin1

There are only two possible structures for an octahedral molecule with a formula of ax4y2. One is when the two y’s are next to each other and the other one is when the two y’s are of the opposite side of the molecule. Different structures can be drawn but only two types of molecule can be formed.

Describe what a moraine is made of and explain how this glacial feature forms.

guajiro [1.7K]

Answer:

A moraine is a ridge. It is formed when till is deposited at the edge of a glacier. Till is the mixture of sediments that a glacier deposits directly on the surface. Till is made up of many particles of many different sizes.
