Part 1. implement a 3-bit up counter using 3 tffs and an and gate. you can use jkffs (tie the j/k inputs to make tffs) or convert dff to tff, whichever preferred. use the 7-segment led to display the output. use bcd-to-7 segment decoder (74ls247) to convert the 4-bit binary values to be displayed in the 7-segment led.

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
