A gas at 155 Kpa and 25 degrees celsius has a volume of 1 L. The pressure increases to 605 kPa as the temperature is raised to 125 degrees Celsius what is the new volume?

The answer to your question is V2 = 0.34 l

Explanation:

Data

Pressure 1 = P1 = 155 kPa

Temperature 1 = T1 = 25°C = 298°K

Volume 1 = V1 = 1 l

Pressure 2 = P2 = 605 kPa

Temperature 2 = T2 = 125°C = 398°K

Volume 2 = V2 = ?

Process

To solve this problem use the Combined gas law.

           P1V1/T1 = P2V2/T2

-Solve for V2

          V2 = P1V1T2 / T1P2

-Substitution

          V2 = (155)(1)(398) / (298)(605)

-Simplification

          V2 = 61690 / 180290

-Result

          V2 = 0.34 l

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
