Which process describe water changing from a liquid state to a gas? condensation evaporation infiltration precipitation

Option (b) is the correct answer.

Explanation:

When we heat a liquid substance then its molecules gain kinetic energy due to which more number of collisions occur between the particles. As a result, liquid state of substance will change into gaseous state.

This process of conversion of liquid into gaseous phase is known as evaporation.

Whereas when gaseous phase changes into liquid state then there occurs decrease in kinetic energy of molecules of a substance. Due to which they change into liquid state. This process is known as condensation.

When two aqueous solution react chemically with each other then an insoluble solid formation into the solution is known as precipitate. This type of reaction is known as precipitation.

When water present on the surface of earth enters into the soil then it is known as infiltration.

Therefore, we can conclude that evaporation process describe water changing from a liquid state to a gas.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
