Starting with a vessel of temperature 50.1°C, a pressure of 6263.MmHg and volume 461.1mL, what is its final volume, in liters, i
il63 [147K]

Answer:

The value of final volume inside the vessel  V_{2} =  5.17 ml

Explanation:

Initial pressure P_{1} = 6263 mm Hg = 8.24 atm = 835 K pa

Initial temperature T_{1} = 50.1 ° c = 323.1 K

Initial volume V_{1} = 461.1 ml =  0.0004611 m^{3}

Final temperature T_{2} = - 95.8 ° c = 177.2 K

Finial pressure P_{2} = 411 atm = 41644.6 K PA

We know that

P_{1} \frac{V_{1} }{T_{1} }  = P_{2} \frac{V_{2} }{T_{2} }

Put all the values in the above equation

⇒ 835 × \frac{0.0004611}{323.1} = 41644.6 × \frac{V_{2} }{177.2}

⇒ V_{2} = 5.07 × 10^{-6} m^{3}

⇒ V_{2} =  5.17 ml

This is the value of final volume inside the vessel.

Bas_tet [7]

Organisms that reproduce sexually have offspring with greater variety because: B. The offspring get DNA from two parents, and it combines randomly.

Reproduction refers to a biological process through which living organisms (parents) mate to produce offspring.

Basically, there are two (2) main types of reproduction and these include;

  • Asexual reproduction.
  • Sexual reproduction.

During sexual reproduction, parent organisms produce offspring with greater variety because the genetic material of their parents are randomly combined to produce genetically-diverse offspring.
