Here are the answers to the questions from the image:

Question 1: Complete the table below during the experiment.

State of Matter	Observation	Temperature
Solid (ice)	Hard, opaque, fixed shape	$0^\circ\text{C}$
Liquid (water)	Clear, fluid, takes shape of container	e.g., $25^\circ\text{C}$
Gas (steam)	Invisible gas, visible mist above boiling water	$100^\circ\text{C}$

Question 2: Explain how ice changed from a solid into a liquid.

Ice absorbs heat energy, causing its particles to gain kinetic energy and vibrate more vigorously.
At the melting point ( $0^\circ\text{C}$ ), the particles have enough energy to overcome some of the strong intermolecular forces holding them in a fixed lattice structure.
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 and the context of the experiment, the boiling point of water is \boxed{\text{}100^\circ\text{C}}}.

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.
