Explanation:

This worksheet is about the properties of water and related molecular concepts, which falls under the subfield of Biology (or Chemistry, as molecular properties are also a chemical topic, but given the context of water's role in life, Biology is also relevant). The blanks are to be filled with terms related to water's polarity, hydrogen bonding, surface tension, capillary action, specific heat, and its role in the primordial soup for life's origin. For example:

• "A molecule with a \(\boldsymbol{positive}\) charged end and a \(\boldsymbol{negative}\) charged end." (polar molecule)
• "\(\boldsymbol{Polar}\) molecules \(\boldsymbol{attract}\) to polar molecules."
• "Polar molecules can \(\boldsymbol{not}\) bond to \(\boldsymbol{non - polar}\) molecules, (ex. oil)."
• "The \(\boldsymbol{cohesion}\) of water that causes \(\boldsymbol{water}\) molecules to stick / \(\boldsymbol{adhere}\) to other \(\boldsymbol{water}\) molecules."
• "Allows water to \(\boldsymbol{overcome}\) gravity." (capillary action)
• "Water requires \(\boldsymbol{large}\) amounts of \(\boldsymbol{energy}\) in order to \(\boldsymbol{change}\) the temperature one degree!" (specific heat)
• "\(\boldsymbol{Water}\) maintains \(\boldsymbol{stable}\) temp."
• "Water must \(\boldsymbol{absorb}\) large amounts of \(\boldsymbol{heat}\) to \(\boldsymbol{boil}\)."
• "Water provides the perfect \(\boldsymbol{aqueous}\) environment for chemical \(\boldsymbol{reactions}\)."
• "\(\boldsymbol{Primordial}\) soup: Early \(\boldsymbol{Earth}\) filled with \(\boldsymbol{organic\ molecules}\) where \(\boldsymbol{life}\) began."

Answer:

• A molecule with a \(\boldsymbol{positive}\) charged end and a \(\boldsymbol{negative}\) charged end.
• \(\boldsymbol{Polar}\) molecules \(\boldsymbol{attract}\) to polar molecules.
• Polar molecules can \(\boldsymbol{not}\) bond to \(\boldsymbol{non - polar}\) molecules, (ex. oil).
• The \(\boldsymbol{cohesion}\) of water that causes \(\boldsymbol{water}\) molecules to stick / \(\boldsymbol{adhere}\) to other \(\boldsymbol{water}\) molecules.
• Allows water to \(\boldsymbol{overcome}\) gravity.
• Water requires \(\boldsymbol{large}\) amounts of \(\boldsymbol{energy}\) in order to \(\boldsymbol{change}\) the temperature one degree!
• \(\boldsymbol{Water}\) maintains \(\boldsymbol{stable}\) temp.
• Water must \(\boldsymbol{absorb}\) large amounts of \(\boldsymbol{heat}\) to \(\boldsymbol{boil}\).
• Water provides the perfect \(\boldsymbol{aqueous}\) environment for chemical \(\boldsymbol{reactions}\).
• \(\boldsymbol{Primordial}\) soup: Early \(\boldsymbol{Earth}\) filled with \(\boldsymbol{organic\ molecules}\) where \(\boldsymbol{life}\) began.
