How many calories are absorbed in a process that absorbs 0.128 joules?
earnstyle [38]

Answer:

There are 0.0305 calories in 0.128 joules

Explanation:

Given that,

Heat absorbed, Q = 0.128 J

We need to find the heat energy absorbed in calories.

We know that the relation between joules and calories is as follows :

1 calorie = 4.184 J

1 J = (1/4.184) J

So,

0.128\ J=\dfrac{0.128 }{4.184}\\\\=0.0305\ cal

So, there are 0.0305 calories in 0.128 joules

A plot of the maxwell distribution of speeds for the same sample of gas at different temperatures shows that.
Eva8 [605]

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.)

An unknown metal has a mass of 86.8 g. When 5040 J of heat are added to the sample, the sample temperature changes by 64.7 ∘ C .
grandymaker [24]

Answer: The specific heat of the unknown metal is 0.897J/g^0C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed=5040 Joules

m= mass of substance = 86.8 g

c = specific heat capacity = ?

Initial temperature of the water = T_i

Final temperature of the water = T_f

Change in temperature ,\Delta T=T_f-T_i=(64.7)^0C

Putting in the values, we get:

5040=86.8\times c\times 64.7^0C

c=0.897J/g^0C

The specific heat of the unknown metal is 0.897J/g^0C
