Calculate the amount of energy (in kj) necessary to convert 497 g of liquid water from 0°c to water vapor at 167°c. the molar heat of vaporization (hvap) of water is 40.79 kj/mol. the specific heat for water is 4.184 j/g · °c, and for steam is 1.99 j/g · °c. (assume that the specific heat values do not change over the range of temperatures in the problem.)

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
