A mining crew extracted two different types of minerals from underground. Then, they transferred the same amount of energy into both minerals. Why did
mineral A change while mineral B stayed the same? Explain what happened to
the molecules of both minerals.

they could be different types of minerals, so one reacted to the energy differently than the other one. and pls answer my latest questions its due by 11:59 pm TONIGHT or i get kicked out of school.. pls help..

Mineral A's molecules had a high level of attraction before. As well as the molecules in mineral B.  But, mineral A's molecules, probably had higher kinetic energy. Which means a higher temperature and faster-moving molecules. Which allowed it to spread more and since it spread more, it became a liquid.  Mineral B might have had not that much kinetic energy so the temperature was colder and its molecules moved slower. That's why probably mineral A changed to a liquid while mineral B remained a Solid.

(Answer + Explanation are both the same thing btw)

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

since electrons are negative the answer is neagtaive
