A gas in a piston–cylinder assembly undergoes a compression process for which the relation between pressure and volume is given
m_a_m_a [10]

Answer:

1.

A=69.8\frac{bar}{m^6}\\\\ B=0.00302bar*m^6

2. W=-8.2kPa

Explanation:

Hello,

1. In this case, for the given p-V equation, one could use the two states to form a 2x2 linear system of equations in terms of A and B:

\left \{ {{0.1^2A+0.1^{-2}B=1} \atop {0.04^2A+0.04^{-2}B=2}} \right.

\left \{ {{0.01A+100B=1} \atop {0.0016A+625B=2}} \right

Whose solution by any method for solving 2x2 linear system of equations (elimination, reduction or substitution) is:

A=69.8\frac{bar}{m^6}\\\\ B=0.00302bar*m^6

2. Now, for us to compute the work, we must first compute n, as the power relating the pressure and volume for this process:

P_1V_1^n=P_2V_2^n\\\\\frac{P_1}{P_2}=(\frac{V_2}{V_1}  )^n\\\\\frac{1bar}{2bar}= (\frac{0.04m^3}{0.1m^3}  )^n\\\\0.5=0.4^n\\\\n=\frac{ln(0.5)}{ln(0.4)} =0.7565

Now, we compute the work:

W=\frac{P_2V_2-P_1V_1}{1-n} =\frac{2bar*0.04m^3-1bar*0.1m^3}{1-0.7565} \\\\W=-0.082bar*m^3*\frac{1x10^2kPa}{1bar}\\ \\W=-8.2kPa

Regards.

Rank the elements in each of the following sets in order of increasing IE₁:
zavuch27 [327]

Explanation:

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Therefore, ionization energy increases along a period.

But when we move from top to bottom in a group then there occurs an increase in size of the atoms. Hence, ionization energy decreases along a group.

(a)  As Sb, Sn and I are all period 5 elements. Hence, these elements are arranged in order of increasing IE_{1} as follows.

                             Sn < Sb < I

(b)  As Sr, Ca, and Ba are all elements of group 2a. Hence, these elements are arranged in order of increasing IE_{1} as follows.

                            Ba < Sr < Ca

A mutation occurs in a cell. Which sequence best represents the correct order of the events involved for this mutation to affect
Eva8 [605]

Answer: A change in the sequence of DNA bases--> Joining amino acids in sequence --> Appearance of characteristics

Explanation:

A mutation is a permanent shift or change from the normal DNA sequence that makes up a gene and affect traits which makes the sequence becomes different from what is commonly found in people. Mutations vary from distortion of a single DNA building block to a large segment of a chromosome.

When mutation occurs in a cell, for the mutation to affect the traits expressed by the particular cell, it must follow this sequence directly:

A change in the sequence of DNA bases--> Joining amino acids in the sequence --> Appearance of characteristics.
