The Freundlich adsorption isotherm is applicable to heterogeneous surfaces and describes how adsorption varies with pressure or concentration, indicating that it is not limited to monolayer adsorption.

The function f(x) = 1/(x-3) is discontinuous at x = 3 because it is undefined at that point.

The function f(x) = x^2 is a quadratic function because it can be expressed in the form ax^2 + bx + c.

The function f(x) = |x| is continuous everywhere, including at x = 0.

The graph of a linear equation is always a straight line.

The graph of a quadratic function is a parabola that can open upwards (if a > 0) or downwards (if a < 0).

Setting y = 0 gives x = 4, indicating that the graph intersects the x-axis at (4, 0).

Rearranging the equation to y = -5/2x + 5 shows that the slope is negative.

In the equation y = mx + b, m represents the slope, which indicates how steep the line is.

The equation y = 2x + 1 has a positive slope of 2 and intersects the y-axis at 1.

The correct statement is that HCF * LCM = Product of the numbers.

The inductive effect decreases with distance from the electronegative atom or group.

The International Date Line is approximately at 180° longitude, is not a straight line, and is not recognized by all countries.

The intersection of two constraint-based sets may contain elements that satisfy the constraints of both sets, and it will be empty if there are no common elements.

The intersection of two hybrid sets contains only the elements that are common to both sets.

The graph of a function and its inverse are symmetric about the line y = x, which is a key property of inverse functions.

The Langmuir adsorption isotherm assumes that adsorption occurs in a monolayer on a surface with a finite number of identical sites.

A solenoid produces a uniform magnetic field inside and negligible field outside when it is long compared to its diameter.

The magnetic field around a long straight conductor decreases with distance from the conductor, following the inverse relationship.

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

The mean free path decreases with increasing pressure because more molecules are present in a given volume, leading to more frequent collisions.

The mesomeric effect is responsible for the stability of resonance structures due to the delocalization of pi electrons.

The distribution of data points shows a right skew, indicating more values on the lower end.

O2 has 2 unpaired electrons in its molecular orbital configuration, making it paramagnetic.

Molecular orbital theory explains the magnetic properties of molecules, such as paramagnetism in O2.

The moment of inertia depends on the mass distribution relative to the axis of rotation.

Zero is neither positive nor negative in any number system.

'100' in base 3 is calculated as 1*3^2 + 0*3^1 + 0*3^0 = 9.

In hexadecimal, 'A' represents the decimal value 10.

36 is a perfect square as it can be expressed as 6 * 6.
