Which side of the water molecule has a slightly negative charge?

• It's all negative

• It's all positive

• Hydrogen

• Oxygen

What kind of Bond does a water molecule have?

• Ionic

• Polar Covalent

• Non Polar Covalent

• Metallic

What is the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules?

• Cohesion

• Surface Tension

• Adhesion

• Polarity

Why is water considered a polar molecule?

• Due to its bent molecular shape and unequal distribution of charges

• Because it is composed of hydrogen and oxygen

• As it can dissolve many substances

• Because it is a liquid at room temperature
