The Density of Water At $0 ^ { \circ } \mathrm { C }$

question 21

Multiple Choice

The density of water at $0 ^ { \circ } \mathrm { C }$ is $999.84 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ and at $4 ^ { \circ } \mathrm { C }$ it is $999.96 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ A 1.0-L container, full to
the brim with water at $4.0 ^ { \circ } \mathrm { C }$ is placed in the refrigerator. By the time that the temperature of the
water reaches $0.0 ^ { \circ } \mathrm { C }$ what volume of water has spilled from the container, assuming that the
contraction of the container is negligible?

• A) \(1.1 \times 10 ^ { - 7 } \mathrm {~m} ^ { 3 }\)
• B) \(14 \times 10 ^ { - 7 } \mathrm {~m} ^ { 3 }\)
• C) \(1.5 \times 10 ^ { - 7 } \mathrm {~m} ^ { 3 }\)
• D) \(1.2 \times 10 ^ { - 7 } \mathrm {~m} ^ { 3 }\)
• E) \(1.3 \times 10 ^ { - 7 } \mathrm {~m} ^ { 3 }\)
