Answer By exposing materials to a hot flame (from a Bunsen
burner typically), the color of the flame can be used to identify
the material. Certain elements give off a characteristic color when
heated to high temperature. See the Related Links for "Wikipedia:
flame test" to the bottom for the answer.

Definition1/11
specific heat capacity of a substance is defined as the QUANITY OF HEAT REQUIRED to raise the temperature of 1 Kg of the substance through 1K ( kelvin ) .
however it obtained the unit of J/kg/k
The specific heat capacity is the energy required to raise the temperature of 1 kg of material by 1 degree Celsius.

Definition1/11
The frequency of a wave, represented by the letter f, is the
number of occurrences of a repeating event per unit time. It is
also referred to as temporal frequency. The SI unit of cycles per
second is called hertz or Hz. Hz can be expressed as a reciprocal
second (s-1 or 1/s).
