When thermal energy is applied to ice, the ice’s temperature rises until 0° C and then stays the same for a period of time. In 1–2 sentences, explain why this takes place.(4 points)
This occurs because the applied thermal energy is used to break the hydrogen bonds holding the ice molecules together, causing the ice to melt. Once all the ice has melted, the temperature remains constant as the thermal energy is used to break the intermolecular forces between water molecules and facilitate the phase change from solid to liquid.
