Front

What is the specific heat capacity of water?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius. It helps regulate Earth's temperature.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between the positive end of one water molecule and the negative end of another, contributing to water's unique properties.

Front

What does H2O represent?

Back

H2O represents a water molecule, which consists of 2 hydrogen atoms and 1 oxygen atom.

Front

What is a molecular compound?

Back

A molecular compound is a chemical compound that consists of molecules formed by the covalent bonding of two or more different elements.

Front

What is cohesion in water?

Back

Cohesion is the property of water that allows water molecules to attract each other, leading to phenomena like surface tension.

Front

What is adhesion in water?

Back

Adhesion is the property of water that allows it to stick to other substances, such as glass, which is important for capillary action.

Front

What is the latent heat of vaporization?

Back

Latent heat of vaporization is the amount of energy required to convert water from liquid to gas without changing its temperature.

Front

Why is water considered a polar molecule?

Back

Water is considered a polar molecule because it has a partial positive charge on one side (hydrogens) and a partial negative charge on the other side (oxygen), leading to its unique properties.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane, allowing small objects to float.

Front

What role does water play in temperature regulation?

Back

Water's high specific heat capacity allows it to absorb and store large amounts of heat, helping to moderate temperatures in the environment.
