Which best describes how geothermal energy is used to make electricity?
a.
rocks are split to release energy that drives a steam turbine attached to an electrical generator.
b.
heat energy from below the ground converts water to steam to drive a steam turbine attached to an electrical generator.
c.
heat energy from below the ground drives liquid water though a turbine attached to an electrical generator.
d.
heat energy from below ground heats and pressurizes air that drives a turbine attached to an electrical generator.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

The energy produced as a result of this flow of electrons from atom to atom is called

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
