Select the correct answer Across a period, the ionization potential [increases, decreases, remains same].

If radius of earth is increased, without chage in its mass, will the length of day increase, decrease or remain same?

Select the correct answer Down the group, electron affinity [increases, decreases, remains same]

The magnifying power of a simple microscope can be increased, if we use eye-piece of

If each data point in a set is increased by 7, does the set's standard deviation increase, decrease, or remain constant?

Fill in the blanks from the choices given below: Across a period, the ionization potential …....... (increases, decreases, remains same).

A : Magnifying power of a simple microscope cannot be increased beyond a limit. R : Magnifying power is inversely proportional to focal length and there are some practical difficulty of grinding, aberrations etc. because of which focal length cannot be decreased below a limt.

As the volume increases with temperature, its density decreases.

Assertion If angle of incidence in case of a prism is gradually increased, then deviation produced by prism will first decrease, then increase. Reason At minimum deviation, r_(1) =A/2 .

Impurities in water will .......... (increase/decrease) its boiling point.
