Answer the following questions based on the descriptions of the images provided. Each answer should be in your own words.
Describe the image of a water molecule.
{The image of a water molecule shows two hydrogen atoms covalently bonded to one oxygen atom. The molecule has a bent shape with an angle approximately 104.5 degrees between the hydrogen atoms, and it is often represented with 'H2O' notation. The oxygen atom is at the centre, with the hydrogen atoms positioned to each side.}
Explain what is depicted in the image illustrating water's high heat capacity.
{The image of a thermometer in a pot of water shows the temperature of water rising slowly as heat is added. The pot is on a stove, and steam can be seen rising from the water. This image emphasizes the concept that water can absorb a lot of heat before its temperature increases significantly.}
Identify and discuss what is shown in the image of ice floating on liquid water.
{The image of a glass of water with ice cubes floating on top displays the phenomenon of density in water. The ice cubes are distinctly visible and floating above the water surface, highlighting the unique property of ice being less dense than liquid water.}
What does the image depicting water's solvent properties illustrate?
{The image of a glass of water with various salt and sugar crystals dissolving showcases the solvent properties of water. The water is clear, and small particles of salt and sugar can be seen mixing into it, demonstrating how water interacts with and solubilises other substances.}
Summarise the image that illustrates the polar nature of water molecules.
{The image of water molecules arranged in a lattice structure shows how adjacent molecules interact. It highlights the partial positive charge of the hydrogen atoms and the partial negative charge of the oxygen atom, indicating the polar nature that allows for hydrogen bonding between molecules.}
