Question

at what temperature does water stop contracting and begin to expand? 0 degrees celsius 4 degrees celsius 32 degrees celsius

Explanation:

This is a basic knowledge question in physics. Water has an unusual property. When cooled from room temperature, it contracts until it reaches 4 degrees Celsius. At 4 degrees Celsius, water reaches its maximum density. Below 4 degrees Celsius, water starts to expand. 0 degrees Celsius is the freezing point of water. 32 degrees Celsius is just a random temperature value in this context and has no relation to the property described in the question.

Answer:

4 degrees Celsius
