Which of these scientific terms is not governed by law?
- A.
  
  Floatation
- B.
  
  Elasticity
- C.
  
  Nuclear fission
- D.
  
  Motion
Correct Answer
C. Nuclear fission

Explanation
Nuclear fission is not governed by a scientific law because it is a process that occurs under specific conditions and is not universally applicable. Scientific laws describe fundamental principles or relationships that are consistent and predictable across different situations. In contrast, nuclear fission is a specific type of nuclear reaction that involves the splitting of an atomic nucleus and is influenced by various factors such as the type of nucleus and the presence of other particles. Therefore, it is not considered a scientific law.

How many laws explains thermodynamics?
- A.
  
  Four laws
- B.
  
  Five laws
- C.
  
  Seven laws
- D.
  
  Six laws
Correct Answer
A. Four laws

Explanation
The correct answer is four laws. Thermodynamics is governed by four fundamental laws which describe the behavior of energy and its transformation in a system. These laws include the zeroth law (which defines thermal equilibrium), the first law (which states the conservation of energy), the second law (which establishes the direction of heat flow), and the third law (which deals with the behavior of systems at absolute zero temperature). These four laws provide a comprehensive framework for understanding and analyzing the principles of thermodynamics.

Which of these is not explained by ideal gas law?
- A.
  
  Avogadro's law
- B.
  
  Boyle's law
- C.
  
  Charles' law
- D.
  
  Newton's law
Correct Answer
D. Newton's law

Explanation
The ideal gas law, which relates the pressure, volume, and temperature of a gas, does not explain Newton's law. Newton's law, also known as Newton's second law of motion, states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. This law is unrelated to the behavior of gases and is instead a fundamental principle in classical mechanics. Therefore, Newton's law is not explained by the ideal gas law.

What does Dalton's law explain?
- A.
  
  Partial pressure
- B.
  
  Mass
- C.
  
  Elasticity
- D.
  
  Motion
Correct Answer
A. Partial pressure

Explanation
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas in the mixture. This law explains how gases behave when they are mixed together, and how their individual pressures contribute to the overall pressure of the mixture. Therefore, the correct answer is Partial pressure.

What does Hooke's law explain?
- A.
  
  Motion
- B.
  
  Thermodynamics
- C.
  
  Elasticity
- D.
  
  Power
Correct Answer
C. Elasticity

Explanation
Hooke's law explains elasticity. Hooke's law states that the force needed to extend or compress a spring by some distance is proportional to that distance. This law helps to understand how materials behave when subjected to external forces and how they return to their original shape after the force is removed. Elasticity is the property of a material to deform under stress and return to its original shape when the stress is removed. Therefore, Hooke's law is directly related to the study of elasticity.

Which of these is not a geophysical law?
- A.
  
  Achie's law
- B.
  
  Birch's law
- C.
  
  Henry's law
- D.
  
  Byerlee's law
Correct Answer
C. Henry's law

Explanation
The correct answer is Henry's law. Henry's law is not a geophysical law, but rather a law in chemistry that describes the relationship between the concentration of a gas in a liquid and the pressure of that gas above the liquid. Geophysical laws, on the other hand, pertain to the study of the Earth's physical properties and processes, such as Achie's law, Birch's law, and Byerlee's law.

Which of these laws explain chemical transport?
- A.
  
  Lamm equation
- B.
  
  Graham's law
- C.
  
  Hess's law
- D.
  
  Fick's law of diffusion
Correct Answer
C. Hess's law

Explanation
Hess's law is not related to chemical transport. It states that the enthalpy change of a reaction is independent of the pathway taken, only dependent on the initial and final states. Therefore, it does not explain chemical transport.

Which of these is not a radiation law?
- A.
  
  Stefan-Boltzmann law
- B.
  
  Radioactive decay law
- C.
  
  Wien's displacement law
- D.
  
  Pauli's exclusion law
Correct Answer
D. Pauli's exclusion law

Explanation
Pauli's exclusion law is not a radiation law because it does not describe the behavior or properties of radiation. Instead, it is a fundamental principle in quantum mechanics that states that no two identical fermions can occupy the same quantum state simultaneously. It is not related to the emission or absorption of radiation, which is the focus of the other three laws mentioned in the question.

Which of these laws is unrelated to optics?
- A.
  
  Hess's law
- B.
  
  Law of reflection
- C.
  
  Snell's law
- D.
  
  Malu's law
Correct Answer
A. Hess's law

Explanation
Hess's law is unrelated to optics because it is a principle in chemistry that states the total enthalpy change of a chemical reaction is independent of the pathway taken. It is used to calculate the enthalpy change of a reaction by manipulating other known reactions. On the other hand, the Law of reflection, Snell's law, and Malu's law are all related to optics. The Law of reflection states that the angle of incidence is equal to the angle of reflection. Snell's law describes the relationship between the angles of incidence and refraction when light passes through different mediums. Malu's law is a mathematical expression that relates the refractive indices of two mediums to the angles of incidence and refraction.

Which of these laws governs electromagnetism?
- A.
  
  Gauss's law
- B.
  
  Lorentz force law
- C.
  
  Dalton's law
- D.
  
  Kopp's law
Correct Answer
A. Gauss's law

Explanation
Gauss's law is the correct answer because it is a fundamental law in electromagnetism that relates the electric flux through a closed surface to the total electric charge enclosed by that surface. It is one of the four Maxwell's equations that form the basis of classical electrodynamics. Lorentz force law, on the other hand, describes the force experienced by a charged particle in an electromagnetic field. Dalton's law relates to the partial pressures of gases in a mixture, and Kopp's law is related to the heat capacities of gases.
