Question

Which of the following best describes the freezing of water?

A.
negative change in enthalpy, low temperature and positive entropy
B.
negative change in enthalpy, low temperature and negative entropy
C.
positive change in enthalpy, low temperature and positive entropy
D.
positive change in enthalpy, low temperature and negative entropy
E.
negative change in enthalpy, high temperature and negative entropy

Answer 1

The best description for the freezing of water is:

A. Negative change in enthalpy, low temperature, and positive entropy.

Freezing involves a decrease in enthalpy (heat is released), typically occurs at low temperatures, and results in a more ordered state (positive entropy change) as water transitions from a liquid to a solid state.
