Few quantities with their units are listed below. Mark the units which are not correctly matched.
(i) Density: kg m-3
(ii) Velocity of light: m s-1
(iii) Planck's constant: J-1 s-1
(iv) Acceleration: m s-2
(v) Force: kg m
Planck's constant = J s
Force = kg m s-2
Match the prefixes present in column I with their multiples in column II and mark the appropriate choice.
pico = 10-12, femto = 10-15, milli = 10-3, giga = 109
Choose the correct statement about I, II and III.
Properties of three sates of matter:
(i) Solids and liquids have definite volume whereas gases don't possess definite volume.
(ii) Three states of matter solid, liquid and gas are interconvertible by changing the temperature and pressure conditions.
(iii) Solids are rigid and have definite shape thus don't possess a large degree of freedom.
Mark the conversion factor which is not correct.
