Answer to Question #113726 in Molecular Biology for MAKHUOGA ALFRED FRIDAY

Question

discussed the Laws of Thermodynamics and their relation to energy and energy transfer. Energy transfers take place constantly in everyday activities. Think of two scenarios: cooking on a stove and driving. Explain how the second law of thermodynamics applies to these two scenarios.

Answer 1

Thermodynamics deals with heat and other forms of energy, and it describes how thermal energy is converted from one form to another. Thermal energy can be described as the energy within a substance due to its difference in temperature. Hence, we have for laws that explain the thermal energy.

The first law of thermodynamics states that "when a system experiences an increase in energy, so does its thermal energy increases, and also the work done on the system increases too."

The second law states that" heat energy can only be transferred from a body of high temperature to a body of lower temperature."

The third law states that"waste energy of a purified crystal when in absolute zero states will be equal to zero."

When cooking with a stove and driving, the heat energy from the burner and the car engine follows the second law of heat transfer when the heat is transferred from the grill to the pot and also from the engine by combustion of fuel to the car wheels respectively resulting kinetic energy that makes the car move and water to boil on the pot.
