Okay, i found this problem to be pretty tough, maybe someone can lend me a hand.(adsbygoogle = window.adsbygoogle || []).push({});

Theres a container with a piston, and theres a gas on the bottom of the piston.

State 1

[itex]A=1.2 x 10^{-2}m^{2}[/itex]

[itex]T_1=0^{\circ{}}C[/itex]

[itex]V_1=1.5 x 10^{-3}m^{3}[/itex]

[itex]P_1=1.02 x 10^{5}Pa[/itex]

State 2

Theres a 150kg weight ontop to the piston, wish causes the piston to go down.

[itex]T_2=0^{\circ{}}C[/itex]

State 3

The cylinder is brought in contact with boiling water raising temperature to [itex]100^{\circ{}}C[/itex]

The weight goes up, the gas pushes up the piston, and the piston pushes up the weight.

[itex]T_3=100^{\circ{}}C[/itex]

State 4

The block is removed, and the gas expands to fill the container, which is a cylinder.

[itex]T_4=100^{\circ{}}C[/itex]

All I need is how to get this started I think I can get it going from there.

The truth is I dont even know how to start this, looked at it for like 30 minutes, maybe I missed something.

But any help would be appreciated.

Thxs.
