A saturated solution contains the maximum amount of solute that can dissolve at a given temperature.

In an exothermic reaction, the enthalpy change (ΔH) is negative because heat is released.

The elastic potential energy stored in a stretched wire is given by U = (1/2) * Y * (ΔL^2 / L), which is proportional to the square of the elongation.

Trailing zeros in a decimal are significant.

Entropy is a measure of disorder in a system, and it tends to increase in spontaneous processes.

Escape velocity is independent of the mass of the object, but it depends on the mass and radius of the Earth.

The Freundlich adsorption isotherm is applicable to heterogeneous surfaces and describes multilayer adsorption.

For a spontaneous process, the Gibbs free energy change (ΔG) is less than 0 (ΔG < 0).

A negative Gibbs free energy change (ΔG < 0) indicates that the process is spontaneous.

Heat capacity depends on the amount of substance; it is not a constant value.

2500 has 2 significant figures unless specified with a decimal point.

A satellite in a low Earth orbit has a shorter orbital period compared to a geostationary satellite due to its closer proximity to Earth.

The period of a satellite in a low Earth orbit is shorter than that of a satellite in a high Earth orbit due to the stronger gravitational pull.

A satellite in a low Earth orbit has a very high orbital speed due to the proximity to the Earth and the gravitational pull.

All the given identities are true for all angles A.

In an endothermic reaction, heat is absorbed, resulting in a positive ΔH.

Neodymium is used in making strong permanent magnets due to its magnetic properties.

CN- is a strong field ligand and causes a large splitting of d-orbitals, leading to low-spin complexes.

The slope of the given line is 4/5. A line parallel to it must have the same slope, hence y = (4/5)x - 3.

Water has a higher boiling point due to strong hydrogen bonding.

Mercury has a very high surface tension due to strong cohesive forces between its molecules, higher than that of water, ethanol, and benzene.

Mercury has the highest surface tension due to strong cohesive forces.

Glycerol is a thick liquid and has a higher viscosity compared to the others.

Benzene has a lower boiling point compared to water, ethanol, and hexane.

Benzene is a non-polar liquid, while the others are polar.

Hexane is a non-polar solvent, while the others are polar.

Ethanol can form strong hydrogen bonds due to the presence of an -OH group.

Ethanol has a lower surface tension compared to water and mercury due to its molecular structure.

Polaroid film is specifically designed to polarize light by allowing only light waves oscillating in a certain direction to pass through.

Rubber is an insulator and has a much higher resistivity compared to metals like copper, aluminum, and silver.
