Two students are engaged in an argument about whether or not a plant can live independently inside of a sealed jar for up to two

weeks by using energy from the sun and energy from the mitochondria to carry out all of its life processes.
Student A: The plant can live independent of other organisms such as animals, because it can obtain nutrients to grow, reproduce, make needed materials, and remove the waste on its own.
Student B: The plant only relies on other organisms, such as animals that produce the carbon dioxide needed to obtain nutrients to grow, reproduce, make needed materials, and remove waste.
Based on the diagram, which student's argument is BEST supported? Use evidence from the diagram to support your reasoning.

The coefficient of thermal expansion α = (1/V)(∂V/∂T)p. Using the equation of state, compute the value of α for an ideal gas. Th
andreyandreev [35.5K]

Answer:

The coefficient of thermal expansion α is  

      \alpha  =  \frac{1}{T}

The coefficient of compressibility

      \beta   =  \frac{1}{P}

Now  considering (\frac{ \delta P }{\delta  T} )V

From equation (1) we have that

       \frac{ \delta P}{\delta  T}  =  \frac{n R }{V}

From  ideal equation

         nR  =  \frac{PV}{T}

So

     \frac{\delta P}{\delta  T}  =  \frac{PV}{TV}

=>  \frac{\delta  P}{\delta  T}  =  \frac{P}{T}

=>   \frac{\delta  P}{\delta  T}  =  \frac{\alpha }{\beta}

Explanation:

From the question we are told that

   The  coefficient of thermal expansion is \alpha  =  \frac{1}{V} *  (\frac{\delta V}{ \delta  P})  P

    The coefficient of compressibility is \beta  =  - (\frac{1}{V} ) *  (\frac{\delta V}{ \delta P} ) T

Generally the ideal gas is  mathematically represented as

        PV  =  nRT

=>      V  =  \frac{nRT}{P}  --- (1)

differentiating both side with respect to T at constant P

       \frac{\delta V}{\delta T }  =  \frac{ n R }{P}

substituting the equation above into \alpha

       \alpha  =  \frac{1}{V} *  ( \frac{ n R }{P})  P

        \alpha  = \frac{nR}{PV}

Recall from ideal gas equation  T =  \frac{PV}{nR}

So

          \alpha  =  \frac{1}{T}

Now differentiate equation (1) above with respect to  P  at constant T

          \frac{\delta  V}{ \delta P}  =  -\frac{nRT}{P^2}

substituting the above  equation into equation of \beta

        \beta  =  - (\frac{1}{V} ) *  (-\frac{nRT}{P^2} ) T

        \beta =\frac{ (\frac{n RT}{PV} )}{P}

Recall from ideal gas equation that

       \frac{PV}{nRT}  =  1

So

       \beta   =  \frac{1}{P}

Now  considering (\frac{ \delta P }{\delta  T} )V

From equation (1) we have that

       \frac{ \delta P}{\delta  T}  =  \frac{n R }{V}

From  ideal equation

         nR  =  \frac{PV}{T}

So

     \frac{\delta P}{\delta  T}  =  \frac{PV}{TV}

=>  \frac{\delta  P}{\delta  T}  =  \frac{P}{T}

=>   \frac{\delta  P}{\delta  T}  =  \frac{\alpha }{\beta}

Answer:

Density, \rho=24.68\ g/cm^3

Explanation:

Mass of a marble slab is 38.6 kg 38600 grams

The dimensions of the marble is 17 cm×23 cm×4 cm

We need to find its density. Mass per unit volume equals density. So,

\rho=\dfrac{m}{V}\\\\\rho=\dfrac{m}{lbh}\\\\\rho=\dfrac{38600\ g}{(17\times 23\times 4)\ cm^3}\\\\\rho=24.68\ g/cm^3

So, the density of the marble slab is 24.68\ g/cm^3

The mass percentage of hydrochloric acid within a solution is 15.00%. given that the density of this solution is 1.075 g/ml, fin
Morgarella [4.7K]

Given the mass percentage of HCl solution = 15.00 %

This means that 15.00 g HCl is present in 100 g solution

Moles of HCl = 15.00 gHCl*\frac{1 mol HCl}{36.46 g HCl} =0.411molHCl

Density of the solution = 1.075 g/mL

Calculating the volume of solution from density and mass:

100 g *\frac{1mL}{1.075 g} =93.0 mL

Converting volume from mL to L:

93.0 mL * \frac{1 L}{1000 mL} =0.093 L

Calculating the molarity of HCl solution from moles and volume:

\frac{0.411 mol}{0.093 L} =4.42 mol/L
