The mode is 12, which appears three times, more than any other number.

The mode is 70, as it appears 3 times, which is more than any other score.

In the Freundlich isotherm, K is the adsorption coefficient that indicates the extent of adsorption.

To find the x-intercepts, set f(x) = 0: x^2 - 4 = 0, which factors to (x - 2)(x + 2) = 0, giving x-intercepts at 2 and -2.

Substituting x = 2 gives f(2) = |2 - 2| = |0| = 0.

The graph of f(x) = |x| forms a V-shape, reflecting the absolute value function.

The absolute value function |x| outputs the positive value of x, regardless of whether x is negative or positive.

The absolute value function returns the non-negative value of x, so f(-3) = 3.

The bar graph shows Product B with the highest sales in Q2.

Product B sold 50 units in Q1, 70 in Q2, 80 in Q3, and 50 in Q4, totaling 250 units.

Product B sold 100 units in Q1 and 150 units in Q2, totaling 250 units.

The energy of the emitted photon is highest for the transition from n=2 to n=1, as it involves the largest energy difference.

'n' represents the number of moles of the gas in the ideal gas equation.

The pressure exerted by a gas is due to the collisions of gas molecules with the walls of the container.

In the kinetic theory of gases, the temperature of a gas is a measure of the average kinetic energy of the molecules.

In elastic collisions, both kinetic energy and momentum are conserved, which is a key assumption in the kinetic theory of gases.

An ideal gas is a theoretical gas that perfectly follows the ideal gas law and has no intermolecular forces, behaving ideally under all conditions.

The mean free path is defined as the average distance a molecule travels before colliding with another molecule.

An ideal gas is defined as a gas that has no intermolecular forces and occupies no volume, allowing it to perfectly obey the ideal gas law under all conditions.

According to the kinetic theory, pressure is directly proportional to the average kinetic energy of the gas molecules, which is proportional to the square of their speed.

In an ideal gas, the internal energy is primarily due to the kinetic energy of the gas molecules, as potential energy is negligible.

In the kinetic theory, the temperature of a gas is a measure of the average kinetic energy of the molecules.

The Langmuir isotherm assumes that all adsorption sites are identical and have the same energy.

'b' in the Langmuir isotherm represents the equilibrium constant related to the adsorption process.

The Langmuir isotherm assumes that adsorption occurs at all pressures, not just high pressures.
