JAMB Physics 2019 Objective — Question 32

Question 32 of 40 from the Joint Admissions and Matriculation Board (JAMB) Physics 2019 Objective paper, with the correct answer and a full explanation.

In what range of temperature is the expansion of water anomalous?

A. +20°C to +28°C
B. -80°C to 76°C
C. +96°C to 100°C
D. 0°C to 4°CCorrect

Explanation

The anomalous expansion of water occurs between 0°C and 4°C: heating water in this range causes it to contract (instead of expand), and cooling it causes it to expand (instead of contract).
