If the boiling point of a certain amount of a liquid is 150 degrees, what is the boiling point of twice that amount of the liquid? (2 points) 150 degrees 75 degrees 300 degrees 100 degrees

Answer : The correct option is 150 degrees.

Explanation :

Extensive property : Extensive property are the property which depend on the amount of substance present.

For example : Mass, volume, energy, enthalpy, etc.

Intensive property : Intensive property are the property which do not depend on the amount of substance present.

For example : Color, boiling point, melting point, density, pressure, etc.

The boiling point is an intensive property because it does not depend on the amount of liquid. So, the boiling point will remain same.

Therefore, the answer is 150 degrees.

Therefore, the answer is 150 degrees.

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
