Which law states that the total amount of energy in an isolated system remains constant?
According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, it can be expressed as:
The law of conservation of mass states that in a chemical reaction, the total mass of the products is equal to the total mass of the reactants. This law is based on the principle of:
According to the law of universal gravitation, the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as:
The Second Law of Thermodynamics states that the entropy of an isolated system always increases over time. This law is often interpreted as a measure of the disorder or randomness in a system. Mathematically, it can be expressed as:
The law of conservation of angular momentum states that the total angular momentum of a system remains constant in the absence of external torque. Mathematically, it can be expressed as:
The law of conservation of charge states that the total electric charge in an isolated system remains constant. This law is based on the principle that electric charge cannot be created or destroyed, only transferred from one object to another.
The law of radioactive decay states that the rate of decay of a radioactive substance is proportional to the amount of the substance present. Mathematically, it can be expressed as:
The law of definite proportions states that a chemical compound always contains the same elements in the same proportion by mass. This law is also known as the law of constant composition.
The law of multiple proportions states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in a simple ratio.
The law of octaves states that the properties of elements vary periodically with their atomic mass. This law was first proposed by:
The law of periodicity states that the properties of elements are periodic functions of their atomic numbers. This law was first proposed by:
The law of conservation of energy states that the total amount of energy in an isolated system remains constant. This law is also known as the first law of thermodynamics.
The law of entropy states that the entropy of an isolated system always increases over time. This law is also known as the second law of thermodynamics.
The law of gravitation states that the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law was first proposed by:
