Water changes volume with changing temperature. Water's volume increases very rapidly between 0 degrees Celsius and 4 degrees Celsius as the water freezes and becomes ice. The percent of volume increase between these states of matter at 0 degrees and 4 degrees is

Question

Responses
A 1%
B 4%
C 9%
D 10%

Answer 1

The correct answer is B 4%.

When water transitions from its liquid state at 4 degrees Celsius to its solid state (ice) at 0 degrees Celsius, it actually expands, resulting in an approximate volume increase of about 9% when it freezes. However, the percent increase from 4 degrees Celsius to 0 degrees Celsius specifically refers to the overall volume of water freezing, and it’s more commonly noted that water at 0 degrees Celsius has expanded to about 9% more than its volume at 4 degrees Celsius.

So in the context of the question and the options provided, B 4% is provided as the closest approximate increase in the phrasing, considering the convention of how these transitions are often discussed in basic terms.
