Areaction inside a cylindrical container with a movable piston causes the volume to change from 12.0 l to 18.0 l while the pressure outside the container remains constant at 0.975 atm. (the volume of a cylinder is v = πr 2h), where h is the height; 1 l atm = 101.325 j) a. what is the value in joules of the work w done during the reaction?

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
