During which process of the water cycle does water change from a gas to a liquid? a. precipitation
b. condensation
c. transpiration
d. evaporation

The correct answer is B.Condensation. The other person who answered this question is wrong, it is NOT A. precipitation.

Option (B) is the correct answer.

Explanation:

Condensation is defined as a process in which vapor state of a substance changes into liquid state.

Precipitation is defined as a reaction in which two aqueous solutions on chemically combining with each other leads to the formation of an insoluble solid substance.

Evaporation is defined as a process in which liquid state of a substance changes into vapor state.

Transpiration is defined as a process in which plants absorb water with the help of their roots and then release water vapor through the pore present in their leaves.

Therefore, we can conclude that during condensation process of the water cycle, water change from a gas to a liquid.

a) the particles of the chair are strongly held together.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
