Front

What type of bond holds multiple water molecules together, creating surface tension?

Back

Hydrogen Bonds

Front

What percentage of the Earth's surface is covered by water?

Back

70%

Front

What type of charge does the hydrogen end of a water molecule have?

Back

Positive charge

Front

What type of charge does the oxygen end of a water molecule have?

Back

Negative charge

Front

What type of chemical bond holds the Oxygen and Hydrogen atoms together to make up a single water molecule?

Back

Covalent bond

Front

Define Hydrogen Bond.

Back

A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Front

What is the molecular formula for water?

Back

H2O

Front

Explain why water is considered a polar molecule.

Back

Water is polar because it has a partial positive charge on one side (hydrogens) and a partial negative charge on the other side (oxygen), leading to unequal sharing of electrons.

Front

What is surface tension in water?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and release large amounts of heat without significant temperature changes, helping to regulate climate.
