Web8 mei 2024 · Melting and Boiling Points: Metals have high melting and boiling point. Tungsten has the highest melting point where as silver has low boiling point. Sodium and potassium have low melting points. Chemical Properties of Metals. Metals are electropositive elements that generally form basic or amphoteric oxides with oxygen. WebTell students they are going to compare how quickly ice melts under different conditions. Ask students to predict what will happen to the ice and water temperature under the following conditions. Predictions can be relative (e.g., “Ice will melt faster in condition A”) or specific (e.g., “Ice will melt in X seconds in condition A”).
