You have access two 7-segment decoder outputs from an existing circuit. these outputs show the numbers 00 through 15. build a circuit to convert the two 7-segment displays, which display decimal, to one 7- segment display, which displays the correct hexadecimal number.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
