What 2 particles make up the total mass of an atom?

It takes lots of energy to change the temperature of large bodies of water, such as lakes and oceans. What is the reason for this?

In a process called transpiration, plants get rid of excess water through pores in the leaves called stomata. This excess water is then released into the atmosphere as part of the water cycle. Which of the following terms best describes how the released water enters the atmosphere?

What happens to hydrophobic molecules when mixed with water ?

What happens to hydrophilic molecules when mixed with water ?

This property of water allows attraction between particles of the same substance (why water is attracted to itself), which results in surface tension (the "skin" on the water’s surface), that allows certain insects to walk on the surface of water.

This property of water is the reason clothing gets wet (or why water sticks to surfaces).
