Properties of Water MCQ - Practice Questions with Answers

Properties of Water

• Water is an important constituent of biochemistry, the study of biological reactions.
• Cells contain approximately 70-90% water.
• Water molecules cling to each other due to hydrogen bonding.
• Water plays a role as an important solvent and determines the pathway taken by the water. 
• Those molecules that can attract water are said to be hydrophilic.
• Nonionized and nonpolar molecules that cannot attract water are said to be hydrophobic.
• Water molecules are cohesive and adhesive.
• Due to cohesion, water shows surface tension. 
• Water has a high heat capacity.
• Water is not a linear molecule. It has a bent shape. This is because the highly electronegative oxygen pulls the electrons from the hydrogen closer and gains a partial negative charge. This makes hydrogen partially positive.
