Hydrogen is a non-metal at room temperature and does not exhibit metallic properties.

Parthenogenesis is a form of asexual reproduction where offspring develop from unfertilized eggs.

Respiration in plants produces more energy than fermentation, as it fully oxidizes glucose in the presence of oxygen.

Both statements are true; solutes affect the colligative properties of solvents.

A galvanic cell converts chemical energy into electrical energy spontaneously.

Alkali metals are good conductors of electricity due to the presence of free-moving electrons.

Alkenes are characterized by the presence of at least one double bond between carbon atoms.

Aromatic compounds are characterized by the presence of a benzene ring, which is a stable cyclic structure.

Electric current is defined as the flow of electrons in a conductor.

Exothermic reactions release heat to the surroundings, resulting in a negative enthalpy change.

Phenols are stronger acids than alcohols due to the resonance stabilization of the phenoxide ion.

Sound waves require a medium (solid, liquid, or gas) to travel and cannot propagate through a vacuum.

Surface tension is a property of liquids that causes them to minimize their surface area, allowing them to form droplets.

The critical angle is defined as the angle of incidence above which total internal reflection occurs, and it is always less than 90 degrees.

The image formed by a plane mirror is virtual, erect, and located behind the mirror at the same distance as the object.

The magnetic field due to a current-carrying loop is strongest at the center of the loop and decreases as you move away from the center.

The magnetic field due to a long straight conductor decreases with increasing distance from the conductor.

Inside a long solenoid, the magnetic field is uniform and parallel to the axis of the solenoid, provided the solenoid is long enough.

According to Ohm's Law, current (I) is directly proportional to voltage (V) when resistance (R) is constant.

A concave lens diverges light rays, and it has a negative focal length.

A convex mirror always forms virtual images and has a negative focal length.

A galvanic cell converts chemical energy into electrical energy spontaneously.

A plane mirror always forms a virtual image that is the same size as the object and is erect.

A concave lens always forms a virtual image that cannot be projected on a screen; hence, a real image cannot be formed.

Aldehydes are generally more reactive than ketones due to the presence of the hydrogen atom attached to the carbonyl carbon.

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 + ...

Electric current flows from positive to negative in a circuit.

Exothermic reactions release heat, resulting in a negative enthalpy change.

Ideal gases are considered to have no volume and no intermolecular forces.
