PLS HELP Geothermal power plants drill deep wells underneath
Earth's surface to pump water that is heated by magma. The steam from this hot water spins a turbine
that is hooked up to a generator that produces electricity. The cold water is then pumped back into
Earth to be reheated.

Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of
using this energy to power homes and businesses? Can you think of any consequences to communities
or the surrounding environment?

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
