Both statements A and B are true regarding electron configurations.

The emission spectrum of hydrogen consists of discrete lines corresponding to specific energy transitions between levels.

The energy levels of an electron in an atom are quantized, meaning they can only take on specific values.

Kp is dependent on temperature and can vary with changes in temperature.

The kinetic molecular theory states that gas particles are in constant random motion.

Molecular orbital theory explains the magnetic properties of molecules, particularly the presence of unpaired electrons.

The photoelectric effect requires a minimum frequency of light known as the threshold frequency.

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

In thermal equilibrium, no heat flows between systems, meaning they are at the same temperature.

Bonding orbitals are lower in energy than antibonding orbitals, which is a fundamental principle of molecular orbital theory.

Raoult's Law indicates that the vapor pressure of a solution is lower than that of the pure solvent due to the presence of solute.

The first law of thermodynamics states that energy can only be transformed from one form to another, not created or destroyed.

According to the kinetic molecular theory, gas particles are in constant motion.

According to the kinetic theory, gas molecules are in constant random motion, which is a fundamental assumption of the theory.

The second law states that heat cannot spontaneously flow from a colder body to a hotter body, which implies that entropy of the universe tends to increase.

A converging lens can form both real images (when the object is outside the focal length) and virtual images (when the object is within the focal length).

A convex lens can produce both real images (when the object is outside the focal length) and virtual images (when the object is within the focal length).

A diverging lens (concave) can only form virtual images.

A satellite in a stable orbit is acted upon by gravitational force, which provides the necessary centripetal force to keep it in orbit.

In an adiabatic process, the system is insulated from heat transfer, meaning no heat is exchanged with the surroundings.

In an endothermic reaction, the enthalpy change (ΔH) is positive as heat is absorbed.

In an exothermic reaction, heat is released, so ΔH is negative.

For an ideal gas, the internal energy depends only on temperature, not on volume or pressure.

In an isobaric process, the pressure remains constant.

Real gases experience intermolecular forces, which causes deviations from ideal behavior.

In a balanced Wheatstone bridge, the potential difference across the galvanometer is zero, indicating no current flow.

A catalyst lowers the activation energy of a reaction, thereby increasing the rate without being consumed.

A potentiometer can measure both AC and DC voltages, but it is primarily used for DC measurements due to its principle of operation.

A saturated solution is in dynamic equilibrium where the rate of dissolution equals the rate of crystallization.

A Wheatstone bridge can be used for both AC and DC circuits to measure resistance.
