Question

1. which of the following is a property of water? * mark only one oval. polarity surface tension expands when freezing all of the above

Explanation:

• Water is a polar molecule due to its bent shape and the difference in electronegativity between oxygen and hydrogen atoms.
• Water has high surface tension because of hydrogen bonding between water molecules at the surface.
• Water expands when freezing. This is because in the solid (ice) state, water molecules form a more open, hexagonal lattice structure due to hydrogen bonding, which makes ice less dense than liquid water.

Answer:

all of the above
