Create a constructor function called settimeconstruct to construct a structure called timehrmin with two fields: hours to hold the hours, and mins to hold the minutes. the function has integer inputs hoursval and minutesval. the constructor function should check if and . if not, the value should be set to 0.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
