5kg of air (r 287 j/kgk) fills a weighted piston-cylinder device at 50 kpa and 0°c. the device is heated until the temperature is 100°c. determine the initial volume, the final volume, and the work done during this process.

143.5 KJ

Explanation:

We have given mass=5 kg

vlaue of R Which is a constant =287 J/kgk

P=50 KPa

T₁=0°C=273K

T₂=100°C=100+273=373K

we know the standard equation of ideal gas=PV=mRT

Here we have to calculate volume using above equation

v₁=\frac{287\times 5\times 273}{50\times 1000}

v₁=7.833

for constant pressure

=

Using this formula

v₂=×7.8351

=10.705

work done = Pdv

=50××(10.7051-7.8351)

=143.5 KJ

answer:
