Who said energy Cannot be created or destroyed?

Who said energy Cannot be created or destroyed?

Albert Einstein

What is it called when matter Cannot be created or destroyed?

Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

What are the 3 laws of thermodynamics?

Traditionally, thermodynamics has recognized three fundamental laws, simply named by an ordinal identification, the first law, the second law, and the third law. The third law of thermodynamics states that a system’s entropy approaches a constant value as the temperature approaches absolute zero.

Why 100 efficient engine is not possible?

It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term.

How does the second law of thermodynamics apply to living organisms?

The second law says that everything goes from order to disorder, that is an increase in entropy. Living things die when the disorder in the system of the living organisms increases to the point where the system can no longer function.

Why does life not violate the second law of thermodynamics?

We can view the entire universe as an isolated system, leading to the conclusion that the entropy of the universe is tending to a maximum. However, all living things maintain a highly ordered, low entropy structure.

How does the 1st and 2nd law of thermodynamics apply to biological systems?

How do the laws of thermodynamics apply to living organisms? The First Law says that energy cannot be created or destroyed. The Second Law says that in any energy conversion, some energy is wasted as heat; moreover, the entropy of any closed system always increases.

Does photosynthesis violate the second law of thermodynamics?

Abstract. An assertion that the primary photochemistry of photosynthesis can violate the Second Law of thermodynamics in certain efficient systems has been put forward by Jennings et al., who maintain their position strongly despite an argument to the contrary by Lavergne.

What is meant by a change in free energy?

The change in the free energy is the maximum amount of work that a thermodynamic system can perform in a process at constant temperature, and its sign indicates whether a process is thermodynamically favorable or forbidden.

Can you live in a house without electricity legally?

You can legally live in a house without electricity. You cannot legally rent or sell a house without electricity.

Can a car alternator power a house?

You can use car alternators to power a home. One method of doing this is to use the alternators to recharge storage batteries. These batteries could then be used to power an inverter, which would produce the AC voltage needed to run the house. Connect the alternator and gas engine together using a V-belt.
