In an adiabatic process, there is no heat exchange with the surroundings, and the temperature of the system changes due to work done on or by the system.

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.

In an isochoric process, the volume of the system remains constant.

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

The complex [Fe(CN)6]3- is a low-spin complex due to the strong field nature of CN- ligands, resulting in paired electrons.

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.

In a double-elimination tournament, a team must lose twice to be eliminated, allowing for a second chance.

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.

Adsorption isotherms describe the relationship between the amount of adsorbate on the adsorbent and its pressure at a constant temperature, illustrating how adsorption varies with pressure.

Adsorption is generally an exothermic process, as it releases energy.

Ampere's Law is primarily applicable to static currents and requires modifications for time-varying fields.

In an arithmetic progression, the difference between consecutive terms is constant, which is the defining property of an AP.

In an endothermic reaction, heat is absorbed from the surroundings.

An ideal gas is considered to have no volume and no intermolecular forces, making option D correct.

For capacitors in parallel, the total capacitance is the sum of the individual capacitances: C_total = C₁ + C₂ + ...

Catalysts provide an alternative pathway with a lower activation energy, thus increasing the reaction rate without being consumed.

Chemisorption involves the formation of a chemical bond and is generally an irreversible process.

Colligative properties depend on the number of solute particles, not their identity.

Coordination compounds can exhibit different colors due to the presence of different ligands and their ability to split d-orbitals.

A number is divisible by 5 if it ends in either 0 or 5.

Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction, not necessarily when concentrations are equal.

Electric current flows from positive to negative in a circuit.

Electric field lines point from positive to negative charges and never cross each other.

Enthalpy is a state function, meaning it depends only on the initial and final states, not the path taken.
