S.I. units are logical and coherent. S.I. system of units is a rationalised system.
Potassium and caesium are used in photoelectric cells. Potassium and caesium emit electrons on exposure to light.
Physical absorption of molecules takes place on surface only In this process, the bonds of the absorbed molecules are broken.
Phenol is a weaker acid than ethanol. Groups with $+M$ effect and $-I$ effect decrease acidity at $m$-position.
Lateral line system is found in fishes and aquatic larval amphibians. Lateral line system has receptors which are the clusters of sensory cells derived from ectoderm.
In an elastic collision of two billiard balls, the total kinetic energy is conserved during the short time of oscillation of the balls (i.e. when they are in contact). Energy spent against friction does not follow the law of conservation of energy.
During an adiabatic process, heat energy is not exchanged between system and its surroundings. The temperature of a gas increases when it undergoes an adiabatic expansion.
Diamond is a bad conductor. Graphite is a good conductor.
Cuprous ion $(Cu^+ )$ is colourless whereas cupric ion $(Cu^{++} )$ is blue in the aqueous solution. Cuprous ion $(Cu^+ )$ has unpaired electrons while cupric ion $(Cu^{++} )$ does not.
Clones are a group of organisms of identical genotype, produced by a single parent through asexual means. Clones exhibit high genetic variations.
Absorption spectrum consists of some bright lines separated by dark spaces. Emission spectrum consists of dark lines.
