Q. Why does heat makes matter to expand?
Answer:-
Water contracts as it cools similar to all other liquids until it reaches a temperature of about 4 degrees Celsius at which point it expands and begins to form into crystals and expanding approximately 9 percent.
6.1 moles of steam at 100 o C are condensed at 100 o C and the resulting water is cooled to 47.1 o C. Calculate the entropy change for this process. (The molar heat capac
