A 2 liter bottle of water that is initially at 20°C is placed into a refrigeration compartment filled with air at 5°C. If the rate at which heat leaves the bottle is equal to 7t–0.8 kW, how long does it take for the water to reach thermodynamic equilibrium with the air in the refrigeration compartment

explanation:

geosphere and hydrosphere.

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

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
