Question

If a gas absorbs 100 j of heat and expands by 500 cm3

Answer 1

Answer:

Step-by-step eHeat absorbed = 200 J

Change in volume = 500Cm^3

Pressure = 2\times 10^5Nm^{-2}

Formula used for change in internal energy when gas expands:

\Delta U=q-w\\\Delta U=q-P\Delta V

Now put all the given values in this formula, we get

\Delta U=200J-[(2\times 10^5Nm^{-2})\times (500Cm^3)]

\Delta U=200J-[(2\times 10^5Nm^{-2})\times (5\times 10^{-4}m^3)]=200J-100Nm=200J-100J=100Jxplanation:
