When ice water at 0°C is heated
A)thermal expansion occurs.
B)thermal contraction occurs.
C)both occur until 4°C is reached

Question

Quizplus · Accepted Answer

When ice water at 0°C is heated, initially thermal contraction occurs due to the increase in temperature causing the molecules to move closer together. However, at 4°C, a unique property of water occurs where it starts to expand due to the formation of hydrogen bonds between the molecules. Therefore, both thermal expansion and contraction occur until 4°C is reached, after which only expansion occurs.
