Question

In making raspberry jelly, 865 g of raspberry juice is combined with 930 g of sugar. The mixture starts at room temperature, 23.0°C, and is slowly heated on a stove until it reaches 220°F. It is then poured into heated jars and allowed to cool. Assume that the juice has the same specific heat as water. The specific heat of sucrose is 0.299 cal/g·°C. Consider the heating process.

(a) Which of the following terms describe(s) this process? (Select all that apply.)

isothermal

isovolumetric

cyclic

isobaric

adiabatic

reversible

isentropic

(b) How much energy does the mixture absorb?

J

(c) What is the minimum change in entropy of the jelly while it is heated?

J/K
