Discuss the entropy changes involved in the preparation and consumption of a hot fudge sundae.

Solution 20DQ Step 1: Hot fudge sundae is a combination of vanilla ice cream, sprinkles, hot chocolate sauce, whipped cream, nuts, and a single cherry on top. So, initially, the entropy of the system will be lo, since the degree of randomness is less due to low temperature of the ice cream. While we are adding hot chocolate sauce, the entropy of the system will start increasing and the temperature of the ice cream will increase and therefore, the entropy of the system will also increase. So, the entropy of the system will increase. Once we consume the ice cream, the ice cream will be melted completely and it will come to its liquid form. So, the entropy of the liquid will be more while comparing with solids. So, the entropy of the hot fudge sundae is having an increasing nature.
