    physics, Work done during a gas expansion?

    If anyone knows how to get the answer to this please help With the pressure held constant at 220 kPa, 45 moles of a monatomic ideal gas expands from an initial volume of 0.75 m^3 to a final volume of 2.0 m^3 How much work was done by the gas during the expansion? In Joules.. What were the...

    physics, adiabatic expansion of a monatomic ideal gas?

    The volume of a monatomic ideal gas doubles in an adiabatic expansion. The pressure of the gas changes by a factor of .315 and the temperature of the gas changes by a factor of .630 IF 105 moles of gas with an initial pressure of 315 kPa and an initial volume of 1.4 m^3 is expanded...

    Physics, Parallel Axis Theorem?

    In order to understand the parallel-axis theorem and its applications it is given that, I=Icm+md^2 where Icm is the moment of inertia about an axis passing through the center of mass, m is the total mass of the object, and I is the moment of inertia about another axis, parallel to the one for...
