A student 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.

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.
