16 is a multiple of 8, as 16 = 8 * 2.

The photoelectric effect requires a minimum threshold frequency; below this frequency, no electrons are emitted regardless of the intensity of the light.

The slope between any two pairs of these points is the same (1), indicating they are collinear.

The rate of a reaction generally increases with increasing temperature.

The rate of reaction decreases with time for a reactant and increases with time for a product.

The second law of thermodynamics introduces the concept of entropy, stating that the total entropy of an isolated system can never decrease over time.

Parallel lines have the same slope, hence their slopes are equal.

This linear equation represents a line, which has infinitely many solutions.

The mixed graph indicates that variable H exhibits a cyclical pattern over the observed period.

The uncertainty principle states that position and momentum cannot be precisely known at the same time.

The union of two sets combines all unique elements from both sets, ensuring that duplicates are not counted more than once.

A potentiometer is not affected by the internal resistance of the source because it measures voltage by balancing it against a known voltage.

The Van der Waals equation accounts for the volume of gas particles and intermolecular forces.

For a graph to represent a function, any vertical line drawn must intersect the graph at most once.

The Wheatstone bridge is primarily used to measure unknown resistances by balancing it against known resistances.

Thermal conductivity is a measure of a material's ability to conduct heat; it varies with material and temperature.

Time zones can vary in width due to political and geographical reasons, not strictly based on longitude.

Total internal reflection occurs when light travels from a denser medium to a rarer medium.

Rajasthan is known for its desert, particularly the Thar Desert.

Assam is known for its extensive tea production.

Assam is the largest producer of tea in India.

Gases can be compressed the most due to the large spaces between particles.

All states of matter can conduct electricity under certain conditions, but liquids and solids are more common conductors.

Both liquids and gases can flow due to the freedom of movement of their particles.

Solids have a definite shape and volume due to closely packed particles.

Solids have a definite shape due to closely packed particles that do not move freely.

Liquids have a definite volume but take the shape of their container.

Solids generally have the highest density due to closely packed particles.

Plasma has the highest kinetic energy as it consists of ionized gases with free-moving charged particles.

Solids have the least amount of energy compared to liquids, gases, and plasma.
