Absolute zero is defined as the temperature at which molecular motion ceases, corresponding to 0 Kelvin.

Absolute zero refers to the lowest possible temperature, at which gas molecules theoretically stop moving, making both A and B correct.

The critical angle occurs when light travels from a denser medium (water) to a less dense medium (air).

The Earth's magnetic field is approximately 1000 times weaker than that of a typical refrigerator magnet.

The efficiency of a Carnot engine is determined by the temperatures of both the hot and cold reservoirs, given by the formula η = 1 - (T_c/T_h).

The electric field (E) between the plates of a parallel plate capacitor is given by the formula E = V/d, where V is the voltage and d is the separation between the plates.

The electric field E due to a dipole at a point along the axial line is given by E = (1/4πε₀) * (2p) / r³.

The electrochemical series arranges elements based on their standard electrode potentials.

The energy stored in a capacitor is given by U = 1/2 CV^2, which shows it is proportional to both charge and voltage.

According to the third law of thermodynamics, the entropy of a perfect crystalline substance at absolute zero is exactly zero.

Kp can be calculated from Kc using the relation Kp = Kc(RT)^(Δn), where Δn is the change in moles of gas. Here, Δn = 2 - 3 = -1, so Kp = Kc(0.0821T)^(-1). Assuming standard conditions, Kp = 4 * (1/RT) = 16.

The escape velocity from the surface of the Earth is approximately 11.2 km/s.

Faraday's first law states that the mass of a substance deposited at an electrode is directly proportional to the quantity of electricity passed through the electrolyte.

The five-kingdom classification system was proposed by Robert Whittaker.

The force (F) on a charged particle in a magnetic field is given by F = qvB sin(θ). The force is maximum when θ = 90 degrees, as sin(90) = 1.

The force on a charged particle in a magnetic field is given by F = qvB sin(θ). The force is maximum when sin(θ) = 1, which occurs at θ = 90 degrees.

Angular frequency (ω) = 2πf = 2π × 5 = 10 rad/s

The Freundlich isotherm is represented by the equation x/m = kP^(1/n), where x is the amount adsorbed, m is the mass of the adsorbent, and P is the pressure.

Fertilization is the process where the male gamete (sperm) fuses with the female gamete (egg) to form a zygote.

The gravitational force depends on the masses of the objects and the distance between them, as per Newton's law of gravitation.

Gravitational potential energy is defined as the work done against gravity to move an object to a height.

The gravitational potential energy is given by the formula U = mgh, where m is mass, g is acceleration due to gravity, and h is height.

The half-life of a first-order reaction is given by t₁/₂ = 0.693/k.

The half-life of a first-order reaction is given by t₁/₂ = 0.693/k.

The heat capacity at constant volume (Cv) is defined as the amount of heat required to raise the temperature of a substance by 1°C at constant volume.

The heat capacity at constant volume (C_v) is defined as the amount of heat added to the system divided by the change in temperature at constant volume.

The impedance (Z) of an RLC circuit is given by Z = √(R² + (X_L - X_C)²), where X_L is the inductive reactance and X_C is the capacitive reactance.

The impedance (Z) of an RLC circuit is minimum when the inductive reactance (X_L) equals the capacitive reactance (X_C), which is the condition for resonance.

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

The magnetic field (B) due to a straight current-carrying conductor at a distance r is given by B = μ₀I/(2πr).
