Question 1 Report

A quantity of water at 0 °C is heated to 30 °C. For each degree rise in temperature, its density will---------
Answer Details
As the temperature of water rises, its density changes due to thermal expansion or contraction. Water is most dense at 4°C, and its density decreases both below and above this temperature. As a result, when water is heated from 0°C to 30°C, its density will decrease with each degree of temperature rise. Therefore, the correct option is "fall steadily."
