Avessel of 0.25 m3 capacity is filled with saturated steam at 1500 kpa. if the vessel is cooled until 25% of the steam has condensed, how much heat is transferred, and what is the final pressure?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
