Answer: caffeine is a compound.

Explanation:

1) As stated c<span>affeine contains hydrogen, carbon, nitrogen, and oxygen atoms in a fixed ratio.

2) The definition of compound is a pure substance formed by chemical bonding of two or more fifferent elements. That means a defined ratio of the elements in the compound, which conferes uniform and equal properties to every part of the compound.

Some examples of compounds are salt (NaCl), water (H2O), vinegard (CH3 COOH).

A mixture combines several elements or compounds, not bonded by chemical bonds but mixed in ratios which may vary.

What is the difference between evaporation and transpiration? What role does each process play in the water cycle?
vazorg [7]

Answer:

Evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.

The evaporation and transpiration plays a major role in the water cycle as they help in formation of clouds and precipitation

Explanation:

Evaporation:

It is the process of formation and transfer of the water vapor from the surface of the liquid into the atmosphere.

Transpiration:

It is the process of transfer of the water vapors in the atmosphere from the pores present in the leaves of the plants.

The water is carried from the ground through the stems to the leaves.

The major difference between the evaporation and transpiration is that the evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.

The evaporation and transpiration plays a major role in the water cycle as these process helps in transfer of the surface water into the atmosphere, which helps in formation of clouds and precipitation.
