In an isobaric process, expansion should result in a decrease in pressure. which of the following must be added to the system to prevent this pressure drop and maintain isobaric conditions? a. heat (q) b. work (w) c. internal energy (u) d. none of these

Option a. Heat (Q)

Explanation:

In an isobaric process, the pressure of the system does not change and remains constant. It is a thermodynamic process which is usually attained by the contraction or expansion in volume such that it do not effect the maintained pressure of the system that would result from transfer of heat and thus isobaric conditions are maintained.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

i think it's 35 meters
