Determine whether each of these processes is reversible or irreversible. drag the appropriate items to their respective bins. bins: reversible and irreversible1) solid melting infinitesimally slowly at its melting point2) a single swing of a real pendulum3) gas condensing infinitesimally slowly at its condensation point4) solid melting infinitesimally slowly above its melting point5) liquid freezing below its freezing point6) liquid freezing infinitesimally slowly at its freezing point7) a single swing of a frictionless pendulum8) liquid vaporizing infinitesimally slowly at its boiling point9) gas condensing below its condensation point10) liquid vaporizing above its boiling point

Explanation:

The concept applied here is the application of change of state as such ,

A reversible reaction is one that can go in both ways, that is the forward reaction can react to produce the product and the backward reaction can also react to give back the reactants. In a reversible reaction, no new substances are formed and the heat evolved is not much compared to Irreversible reaction.

An Irreversible reaction is one that can not go in both ways. i.e reactants can react to give products but products cant react to give back the reactants. In irreversible reaction, new substances are formed and a huge amount of heat is evolved.

There is reversibility between melting point and freezing point, the differences is if the solid is melting above its melting point, in such case, it is an irreversible reaction.

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
