If energy is added to a boiling liquid, what happens to the temperature of the liquid? A. It decreases
B. It does not change.
C The change cannot be determined.
DIt increases.

When energy is added to a boiling liquid, the temperature of the liquid does not change. In fact, the added energy is used to break bonds between the liquid molecules and let them escape from the liquid itself, allowing the phase change into a gas. More generally, during a phase change the temperature of the system does not change.

Explanation:For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. ... When energy is added to a liquid at the boiling temperature, its converts the liquid into a gas at the same temperature.

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
