The first law of thermodynamics states that the total energy of a system remains constant, even if it is converted from one form to another. For example, kinetic energy—the energy that an object possesses when it moves—is converted to heat energy when a driver presses the brakes on the car to slow it down.
System and Surroundings The premise is that any change in energy of a system will result in an equal but opposite change in the surroundings. This essentially summarizes the First Law of Thermodynamics which states that energy cannot be created nor destroyed.Aug 15, 2020
Examples of the second law of thermodynamics For example, when a hot object is placed in contact with a cold object, heat flows from the hotter one to the colder one, never spontaneously from colder to hotter. If heat were to leave the colder object and pass to the hotter one, energy could still be conserved.
According to the second law of thermodynamics, which of the following is true? - The decrease in entropy associated with life must be compensated for by increased entropy in the environment in which life exists.
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed.

Which of the following is an example of the second law of thermodynamics? The aerobic respiration of glucose generates heat. Photosynthesis enables plants to create energy from sunlight.
In philosophy of physics: Thermodynamics. The second law of thermodynamics states that the total entropy of an isolated system (the thermal energy per unit temperature that is unavailable for doing useful work) can never decrease.
The second law of thermodynamics states that the total entropy can only increase over time for an isolated system, meaning a system which neither energy nor matter can enter or leave.
The second law of thermodynamics says that the entropy of any isolated system always increases. Isolated systems spontaneously evolve towards thermal equilibrium—the state of maximum entropy of the system. More simply put: the entropy of the universe (the ultimate isolated system) only increases and never decreases.
Answer: c) When an isolated system undergoes a spontaneous change, the entropy of the system will increase.
Which of the following are true according to the first law of thermodynamics? Energy can be transferred or transformed from one form to another.
