During convection, warm air rises due to its lower density and cool air falls, creating a continuous cycle driven by temperature and density differences, expressed by the ideal gas law $PV = nRT$.

Boiling water primarily involves convection as the dominant heat transfer mechanism, with conduction at the pot-water interface and minimal radiation.

Sound waves travel faster through denser materials because the molecules in a tightly packed medium collide more frequently, as given by $v = \sqrt{\frac{E}{\rho}}$.

The result of the equation $5 \times 5 - 2 + 1 \times 2$ is $\boxed{25}$.

The expression that shows the quotient of a number $n$ and 4 is $\frac{n}{4}$.

The quotient of the complex number $4 - 3i$ divided by its conjugate is $\frac{7}{25} - \frac{24}{25}i$.

A single nucleotide deletion during DNA replication causes the amino acids encoded by nucleotides after the deletion to be incorrect, resulting in a frameshift mutation.

The square root of 51, represented as $\sqrt{51}$, is irrational because it cannot be expressed as a fraction of two integers.
