What are real life examples of work not being done

Maybe moving boxes from one place to another.

Work is zero if applied force is zero (W=0 if F=0): If a block is moving on a smooth horizontal surface (friction-less), No work will be done. Note that the block may have large displacement but no work gets done.

Gas A=1,06 atm

Gas B=,53 atm

Explanation:

YOu have 3 moles of two different gases mixed into an specific container, the partial pressure is the pressure that each one of them would have if contained in the same container by themselves, as you have 3 moles of substance you just divde 1,6 atm by the 3 moles and assign each gas its correspondent pressure:

1,6/3=,53

Gas A=1,06 atm

Gas B=,53 atm
