12.2 First law of Thermodynamics: Thermal Energy and Work
Energy is transferred along with the genetic material and so obeys the first law of thermodynamics. Energy is transferred—not created or destroyed—in the process. When work is done on a cell or heat transfers energy to a cell, the cell''s internal energy increases. When a cell does work or loses heat, its internal energy decreases.
Ocean thermal energy conversion
Ocean Thermal Energy Conversion (OTEC) systems use a temperature difference (of at least 20° Celsius or 36° Fahrenheit) to power a turbine to produce electricity.
