One summer day, you decide to make a popsicle. You place a popsicle stick into a 9-oz glass of orange juice, which is at room temperature (71 °F). You then place the glass into the freezer which is at âˆ'15 °F and has a cooling power of 7800 BTU/h. How long does it take your popsicle to freeze? (Assume orange juice has the same specific heat as water.)
