Some crystals are formed quickly when volcanic rock cools how would those crystals compare to rock crystals that are formed over hundreds of years deep in the earth why

due to huge amount of rocks containing many nutrients and more temperature and pressure due contraction and expansion

Explanation:

and due to pressure volcanic eruption is done and when it cools the nutrients and mixture of metals also cool forming volcanic crystals

"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"
