Exam Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) It is necessary to determine the specific heat of an unknown object. The mass of the object is 500 g. It is determined experimentally that it takes 16.0 J to raise the temperature 10.0 e Kelvin. Find the specific heat of the object. A) 3 J/kg o K B) 15J/kg o K C) 7 J/kg o K D) 1 J/kg o K E) 0.3J/kg o K 1) 2) Assume you have an ice/water/steam mixture at the triple point. What happens as you increase the pressure at constant temperature? A) The volume decreases, but otherwise nothing happens. B) The steam and ice turns into water. C) The water and steam turns into ice. D) The ice and water turns into steam. 2) 3) Assume you increase the temperature of a liguid at constant pressure slightly below the critical point, then increase the pressure above the critical point, and cool the liquid back down, then decrease the pressure to return to the starting point. What phase transitions are you
