    Thermally isolated cylinder - work done and temperature changes in each chamber

    It's from w=-integral between V1 and V2 (p dV) That then leads to -[pv]between v1 and v2 which then leads to -[pv1]-[pv2] ?

    Thermally isolated cylinder - work done and temperature changes in each chamber

    Following this, how do I work out the change in temperature in chamber B?

    Thermally isolated cylinder - work done and temperature changes in each chamber

    P1V1/P2=V2=8.79 litres I can then use W=-(P2xV1)-(P2vV2) =2227.55J?

    Thermally isolated cylinder - work done and temperature changes in each chamber

    It's until equilibrium is reached, so they'll be the same? I wasn't sure because the piston is thermally insulating

    Thermally isolated cylinder - work done and temperature changes in each chamber

    Homework Statement There is a closed, thermally insulated cylinder, separated into two chambers by a moveable, frictionless, gas-tight, thermally insulating piston. Initial, the volume of each chamber is 3 liters, and each contains an identical monoatomic ideal gas at pressure of 1 atmosphere...

    Need Help Calculating Energy Required to Raise Magnesium Temp

    Any help on this quistion would be greatly appreciated. I have no idea ho to answere it, and can't find anything in my nothes or books anywhere. The temperature-dependent molar specific heat capacity at constant pressure of many substances is given by: c =a+2bT−cT^−2 For magnesium, the...
