The same sample of gas at different temperatures shows that at low

temperatures, most molecules have speeds close to their average

speed.

<h3>What does the Maxwell-Boltzmann distribution graph show?</h3>

Put simply, a Maxwell-Boltzmann distribution graph shows how the energy of gas particles varies within a system.

This is solely a measurement of the speeds of particles because kinetic energy is directly related to speed.

The Maxwell-Boltzmann distribution in chemistry is the subject of this article.

We will begin by describing how to read a graph of the Maxwell-Boltzmann distribution. This will involve taking a closer look at things like the typical energy and the most likely energy.

The graph will then be changed under various circumstances, such as when a catalyst is added or the temperature is raised.

The Maxwell-Boltzmann distribution, which we previously mentioned, is a probability function that depicts the distribution of energy among the particles of an ideal gas. (For more information on this topic, see Chemical Kinetics.)

A plot of the maxwell distribution of speeds for the same sample of gas at different temperatures shows that at low temperatures, most molecules have speeds close to their average speed.

<h3>What is the maxwell distribution of speed?</h3>

The distribution of energy between identical but distinct particles is the subject of the Maxwell-Boltzmann distribution.

The distribution of speeds for gas at a specific temperature is specified by the Maxwell-Boltzmann equation, which is the foundation of the kinetic theory of gases.

The speed that is most likely to occur, the speed that is average, and the root-mean-square speed can all be calculated using this distribution function.

The number of molecules moving at a given speed is represented by the Maxwell-Boltzmann graph's y-axis.

Therefore, if the graph is higher in a certain area, it indicates that there are more gas molecules traveling at such speeds in that area.

Sholpan [36]

Answer:

3.58J/g°C is the specific heat of the metal

Explanation:

The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:

Q = S*ΔT*m

<em>Where Q is energy = 1362J</em>

<em>S is specific heat of the material</em>

<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>

<em>And m is the mass of the material = 15.2g</em>

Replacing:

S = Q / ΔT*m

S = 1362J / 25°C*15.2g

<h3>3.58J/g°C is the specific heat of the metal</h3>

Hydrogen gas is explosive within the range of 4% - 75% v/v. Assuming that each student in your class produces 6 L of H2 and that

yan [13]

In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
