Question

experiment with the water molecules by adding and removing heat. note the phase changes.

1. what is the approximate the melting point of water in celsius?

(hint: check the temperature when this phase change occurs.)
20

Explanation:

Step1: Recall the phase change of water

When water changes from solid (ice) to liquid, this phase change is melting. The temperature at which this occurs under standard atmospheric pressure is a known value.

Step2: Determine the melting point

The melting point of water (the temperature at which ice melts to liquid water) at standard pressure is approximately \(0^\circ \text{C}\).

Answer:

\(0^\circ \text{C}\)
