One helium tank has volume of 2 m^3 , pressure of 400 kpa and temperature of 27°c. second helium tank has volume of 6 m^3, pressure of 200 kpa and temperature of 127 °c. we connect the tanks with a hose. find the pressure and the temperature when the equilibrium is reached.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
