88 An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 12 kmol of an ideal gas at 330 kPa and 508C, and the other side is evacuated. The partition is now removed, and the gas fills the entire tank. Determine the total entropy change during this process. 69.2 kJ/K

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
