Here are the answers to your questions: Question 1: Complete the table below during the experiment. | State of Matter | Observation | Temperature | | :-------------- | :---------------------------------------------- | :-------------------- | | Solid (ice) | Hard, opaque, fixed shape | 0^ | | Liquid (water) | Clear, fluid, takes shape of container | e.g., 25^ | | Gas (steam) | Invisible gas, visible mist above boiling water | 100^ | Question 2: Explain how ice changed from a solid into a liquid. Step 1: When ice absorbs heat energy, its particles gain kinetic energy and vibrate more vigorously. Step 2: At the melting point (0^), the particles have enough energy to overcome some of the strong intermolecular forces holding them in a fixed lattice structure. Step 3: This allows the particles to move past each other, changing from a solid to a liquid state. Question 2 (as numbered on the paper): What boiling point of water was recorded during the experiment? Based on the typical properties of water under standard atmospheric pressure, the boiling point of water is 100^. Question 4: State ONE precautionary measure that should be taken into consideration when conducting this investigation. A key precautionary measure is to wear safety goggles to protect the eyes from splashes or steam. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
