Astudent wants to measure the entropy of ice. what should the student do?
use a thermometer, calorimeter, ice, and distilled water- be sure to repeat.
look up values in a table of thermodynamic data and use hess' law.
the student can't measure entropy directly, only an entropy change.
use a balance, styrofoam cup, thermometer, and ice- repeat three times.

Option (c) is the correct answer.

Explanation:

Entropy is defined as the degree of randomness. This means that more is the number of collisions taking place between atoms of a substance more will be the randomness.

Therefore, more will be the entropy of substance. We cannot measure the entropy but we can measure the change in entropy of a substance.

A thermometer is a glass tube that contains a liquid column generally mercury, and it is usually used to measure the temperature of human body.

A calorimeter is a device or apparatus that is used in a chemical reaction to measure the amount of heat involved.

Therefore, we can conclude that the student can't measure entropy directly, only an entropy change.

i believe the answer is a.
