How much heat is absorbed by 20g granite boulder as energy from the sun causes its temperature to change from 10°C to 29°C? (Specific heat capacity of granite is 0.41 J/gºC)

indium, and thallium have three electrons i think

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

it's c (engineer's do their work with mechanical stuff not on any living being)
