The second law of thermodynamics states that the entropy of an isolated system never decreases over time.

Calorimetry states that the heat absorbed or released by a substance is proportional to the change in temperature.

Faraday's Law states that the induced emf in a closed loop is equal to the negative rate of change of magnetic flux through the loop.

Faraday's Law of electromagnetic induction states that the induced electromotive force in any closed circuit is equal to the rate of change of magnetic flux through the circuit.

Faraday's Law states that the induced EMF is proportional to the rate of change of magnetic flux.

Faraday's Law states that the induced EMF in a closed loop is equal to the negative rate of change of magnetic flux through the loop.

Gay-Lussac's Law states that the pressure of a gas is directly proportional to its temperature at constant volume.

Fourier's Law states that the rate of heat transfer through a material is proportional to the temperature difference across it.

Random errors are caused by unpredictable fluctuations in the measurement process, often due to environmental factors.

Ductile materials can be stretched into wires without breaking.

According to Archimedes' principle, the buoyant force on a submerged object is equal to the weight of the fluid displaced by the object.

Quantization means that energy levels in an atom are discrete, not continuous.

The emission spectrum of hydrogen is a line spectrum, consisting of discrete lines corresponding to specific wavelengths of light emitted by electrons transitioning between energy levels.

An ideal fluid is defined as being incompressible and non-viscous, meaning it has no internal friction.

Viscosity is the measure of a fluid's resistance to flow. Higher viscosity means the fluid flows less easily.

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.

A Light Emitting Diode (LED) is based on the principle of a p-n junction, emitting light when current flows through it.

All of the above devices operate on the principle of electromagnetic induction.

An electric motor uses electromagnetic induction to convert electrical energy into mechanical energy.

An electric motor operates based on the magnetic effects of current, converting electrical energy into mechanical energy.

A transformer uses the principle of electromagnetic induction to transfer electrical energy between circuits.

An electric motor operates on the principle of electromagnetism, converting electrical energy into mechanical energy.

The shape of the objects does not affect the gravitational force; only mass and distance do.

The color of the objects does not affect the gravitational force between them.

The length of the specimen does not affect tensile strength; it is an intrinsic property of the material.

Helium behaves most like an ideal gas due to its low intermolecular forces and small size, making it closer to the ideal gas behavior.

At the same temperature, lighter gases have higher average speeds. Hydrogen (H2) has the lowest molar mass and thus the highest average speed.

A diode allows current to flow in one direction only, making it a unidirectional device.

Semiconductors have zero conductivity at absolute zero and their conductivity increases with temperature.

A Zener diode is designed to operate in reverse bias and maintain a constant voltage.
